Skype is a pioneering cross-platform VoIP and instant messaging application that revolutionized global internet communication. Initially known for its peer-to-peer (P2P) architecture that enabled low-cost international calls, it grew to become one of the most widely used communication tools worldwide before being officially discontinued by its parent company Microsoft in 2025, with users migrated to Microsoft Teams.

Competitive Evolution of Skype

Skype once led the global VoIP and instant messaging market, but its position eroded steadily due to growing competition and internal challenges:

  1. 'Enterprise-focused competitors': Microsoft Teams, Google Meet and Zoom all targeted business users with integrated productivity features, which were Skype's core user group before the shift to remote work.
  2. 'Mobile-first messaging apps': WhatsApp and Telegram offered lighter, more streamlined mobile experiences that outperformed Skype's relatively bulky and resource-heavy mobile client.
  3. 'Specialized team tools': Slack and similar workplace communication platforms carved out niches in corporate team collaboration, focusing on workflow integration rather than basic calling.

The downfall of Skype was accelerated by its failure to adapt to the mobile internet era, strategic misjudgments like adding unnecessary social features, and Microsoft's strategic shift of resources to Microsoft Teams, which ultimately replaced it as the company's primary communication product.

Skype is a historically iconic brand in the global internet communications sector, credited with pioneering accessible cross-border voice and video communication that disrupted traditional telecommunications pricing models. For nearly two decades, it was the leading global brand for consumer VoIP calling and early remote work video conferencing, building widespread recognition among both personal and professional users. As a trailblazer in peer-to-peer internet telephony, its legacy as an industry innovator remains intact even after its formal discontinuation by parent company Microsoft in 2025.

Skype’s active brand strength declined steadily from the mid-2010s onward, driven by growing competitive pressure from mobile-first messaging apps, enterprise-focused collaboration tools, and the strategic reallocation of corporate resources to Microsoft Teams. It failed to adapt to the shift to mobile internet, retaining a bulky, resource-heavy client that fell behind lighter, more streamlined competitors. Internal missteps, including the addition of unnecessary social features that alienated core users, further eroded its market position.

Today, Skype exists as a legacy brand rather than an active commercial asset. While it no longer has an active user base or ongoing product development, it retains high residual brand recognition among users who adopted it during its peak years, and its pioneering role continues to shape the design of modern communication tools.

Brand leadership

Score: 35/100

Skype held unrivaled global leadership in the consumer VoIP segment at its peak in the 2000s, capturing a significant share of the international calling market and becoming synonymous with internet-based communication. However, following its acquisition by Microsoft and the rise of competing products, it gradually lost market relevance, with active leadership ending entirely upon its 2025 discontinuation.

User brand interaction

Score: 40/100

At its peak, Skype counted hundreds of millions of monthly active users across personal and professional segments, with high levels of regular engagement for calls, messaging, and video conferences. After the announcement of its discontinuation and the migration of users to Microsoft Teams, direct interaction with the Skype brand has fallen dramatically, with almost no active engagement today.

Brand growth momentum

Score: 5/100

Skype has recorded negative growth momentum for more than a decade, as user counts and market share declined steadily amid competition and corporate redirection. With its formal discontinuation in 2025, there are no active growth or development plans for the Skype brand, resulting in near-zero ongoing momentum.

Brand stability

Score: 20/100

While Skype’s intellectual property and trademark remain under the ownership of Microsoft, the brand is no longer supported, updated, or actively marketed. The discontinuation of all services eliminated operational stability, leaving the brand with only minimal residual stability as a held intellectual asset.

Brand age

Score: 90/100

Skype was first publicly launched in 2003, giving it over 22 years of brand history as of 2026, making it one of the longest-enduring mainstream consumer internet communication brands. Its long operating history allowed it to build deep brand recognition that persists even after its exit from the market.

Industry profile

Score: 80/100

Skype holds an exceptionally high profile in the global technology and telecommunications industry, widely recognized as a pioneering disruptor that overturned traditional telecom pricing structures for international calling. Its trajectory from startup to acquisition and eventual discontinuation is a common case study for brand and market evolution, cementing its ongoing high industry profile.

Global brand penetration

Score: 75/100

At its peak, Skype was available in more than 100 languages and operated in nearly every country worldwide, building a truly global user base. It was particularly popular for cross-border personal and business communication, helping it establish strong global recognition. Even after discontinuation, residual global awareness of the brand remains high among former users.

Skype was a proprietary telecommunications application operated by Skype Technologies, a division of Microsoft, best known for IP-based videotelephony, videoconferencing and voice calls. It also had instant messaging, file transfer, debit-based calls to landline and mobile telephones (over traditional telephone networks), and other features. It was available on various desktop, mobile, and video game console platforms.

Skype was created by Niklas Zennström, Janus Friis, and four Estonian developers, and first released in August 2003. In September 2005, eBay acquired it for $2.6 billion.[2] In September 2009,[3] Silver Lake, Andreessen Horowitz, and the Canada Pension Plan Investment Board bought 65% of Skype for $1.9 billion from eBay, valuing the business at $2.92 billion. In May 2011, Microsoft bought Skype for $8.5 billion and used it to replace its own Windows Live Messenger. As of 2011, most of the development team and 44% of all the division's employees were in Tallinn and Tartu, Estonia.[4][5][6]

Skype originally featured a hybrid peer-to-peer and client–server system.[7] It became entirely powered by Microsoft-operated supernodes in May 2012;[8] in 2017, it changed from a peer-to-peer service to a centralized Azure-based service. In February 2023, it was used by 36 million people each day.[9]

The service was retired on 5 May 2025,[10][11][12] and the website now redirects users to Microsoft Teams; however, the Skype Dial Pad remains functional for users with paid services.[13][14]

Etymology

The name for the software was derived from the words "sky" and "peer-to-peer", the latter of which described the software's network architecture.[7] This was then abbreviated to "Skyper"; however, some of the domain names for Skyper were already taken.[15] By dropping the final "r", the title became "Skype", for which domain names were available at the time.[16]

History

Skype was founded in 2003 by Niklas Zennström, from Sweden, and Janus Friis, from Denmark.[17] The software was created by Estonians Ahti Heinla, Priit Kasesalu, Jaan Tallinn, and Toivo Annus.[18] Friis and Annus are credited with the idea of reducing the cost of voice calls by using a P2P protocol like that of Kazaa.[19] An early alpha version was created and tested in spring 2003, and the first public beta version was released on 29 August 2003.[20][19]

In June 2005, Skype entered an agreement with Polish web portal Onet.pl for an integrated offering on the Polish market.[21] On 12 September 2005, eBay Inc. agreed to acquire Luxembourg-based Skype Technologies SA for approximately US$2.5 billion in up-front cash and eBay stock, plus potential performance-based consideration.[22] On 1 September 2009, eBay announced it was selling 65% of Skype to Silver Lake, Andreessen Horowitz, and the Canada Pension Plan Investment Board for US$1.9 billion, valuing Skype at US$2.75 billion.[23] On 14 July 2011, Skype partnered with Comcast to bring its video chat service to Comcast subscribers via HDTV sets.[24]

On 17 June 2013, Skype released free video messaging services for Windows, Mac OS, iOS, iPadOS, Android, and BlackBerry.[25]

Between 2017 and 2020, Skype collaborated with PayPal to provide a money-send feature, enabling users to transfer funds via the Skype mobile app in the middle of a conversation.[26]

Microsoft acquisition

On 10 May 2011, Microsoft Corporation acquired Skype Communications, S.à r.l for US$8.5 billion.[27] It was incorporated as a division of Microsoft, which acquired all its technologies with the purchase. The acquisition was completed on 13 October 2011.[27][28] Microsoft began integrating the Skype service with its own products. Along with taking over the development of existing Skype desktop and mobile apps, it developed a dedicated client app for its then-newly released, touch-focused Windows 8 and Windows RT operating systems, which were made available from Windows Store when the then-new OS launched on 26 October 2012. The following year, it became the default messaging app for Windows 8.1, replacing the Windows 8 Messaging app at the time, and was pre-installed on every device that came with or upgraded to 8.1.[29]

In a month-long transition from 8 to 30 April 2013, Microsoft discontinued two of its own products in favor of Skype, including its Windows Live Messenger instant messaging service, although Messenger continued to be available in mainland China until October 2014.[30][31]

On 11 November 2014, Microsoft announced that in 2015, its Lync product would be replaced by Skype for Business, combining the features of Lync and the consumer Skype software. Organizations that used it could switch their users between the default Skype for Business interface and the Lync interface.[32]

Post-acquisition

On 12 August 2013, Skype released the 4.10 update for Apple iPhone and iPad apps that allowed HD quality video for iPhone 5 and fourth-generation iPads.[33]

On 20 November 2014, Microsoft Office's team announced that a new chat powered by Skype would be implemented in their software, enabling users to chat with co-workers in the same document.[34]

On 15 September 2015, Skype announced the release of Mojis ("a brand new way to express yourself on Skype")—short video clips and GIFs featuring characters from films and TV shows that could be entered into conversations like emoticons. Skype worked with Universal Studios, Disney Muppets, BBC and other studios to enhance the Mojis collection.[35] Later that year, Gurdeep Singh Pall, Corporate Vice President of Skype, announced that Microsoft had acquired the technology from Talko.[36]

In July 2016, Skype introduced an early Alpha version of a new Skype for Linux client, built with WebRTC technology, after several petitions asked Microsoft to continue development for Linux.[37][38] In September of that year, Skype updated their iOS app with new features, including an option to call contacts on Skype through Siri voice commands.[39] In October of that year, Microsoft launched Skype for Business for Mac.[40]

In February 2017, Microsoft announced plans to discontinue its Skype Wi-Fi service globally. The application was delisted, and the service itself became non-functional from 31 March 2017.[41][42] On 5 June 2017, Microsoft announced its plans to revamp Skype with similar features to Snapchat, allowing users to share temporary copies of their photos and video files.[43] In late June 2017, Microsoft rolled out their latest update for iOS, incorporating a revamped design and new third-party integrations, with platforms including Gfycat, YouTube, and UpWorthy.[44] It was not well-received, with numerous negative reviews and complaints that the new client broke existing functionality.[45] Skype later removed this "makeover". In December 2017, Microsoft added "Skype Interviews", a shared code editing system for those wishing to hold job interviews for programming roles.[46][47]

In April 2017, Microsoft eventually moved the service from a peer-to-peer to a central server based system, enabling cloud-based storage of text messages/pictures and temporary 30-day storage of videos/file attachments/voice messages/call recordings.[48] It also adjusted the user interfaces of apps to make text-based messaging more prominent than voice calling. Skype for Windows,[49] iOS,[50] Android,[51] Mac[52] and Linux[53] all received significant visual overhauls at this time. Users with legacy Skype accounts were able to retain their usernames, while new users are no longer able to manually choose a username. New user registrations associated with a Microsoft account were assigned a username with a for a call.[138]

Security and privacy

Skype was claimed initially to be a secure communication, with one of its early web pages stating "highly secure with end-to-end encryption".[139] Security services were invisible to the user, and encryption could not be disabled. Skype claimed to use publicly documented, widely trusted encryption techniques for Skype-to-Skype communication: RSA for key negotiation and the Advanced Encryption Standard to encrypt conversations.[140] However, it is impossible to verify that these algorithms are used correctly, completely, and at all times, as there is no public review possible without a protocol specification or the program's source code. Skype provided an uncontrolled registration system for users with no proof of identity. Instead, users might choose a screen name that does not have to relate to their real-life identity in any way; a name chosen could also be an impersonation attempt, where the user claims to be someone else for fraudulent purposes. A third-party paper analyzing the security and methodology of Skype was presented at Black Hat Europe 2006. It analyzed Skype and found a number of security issues with the then-current security model.[141]

Skype incorporated some features that tended to hide its traffic, but it was not specifically designed to thwart traffic analysis and therefore did not provide anonymous communication. Some researchers had been able to watermark the traffic so that it was identifiable even after passing through an anonymizing network.[143]

In an interview, Kurt Sauer, the Chief Security Officer of Skype, said, "We provide a safe communication option. I will not tell you whether we can listen or not."[144] This did not deny the fact that the U.S. National Security Agency (NSA) monitored Skype conversations. Skype's client used an undocumented and proprietary protocol. The Free Software Foundation (FSF) was concerned about user privacy issues arising from using proprietary software and protocols and had made a replacement for Skype one of their high-priority projects.[145] Security researchers Biondi and Desclaux had speculated that Skype might have a back door, since Skype sent traffic even when it was turned off and because Skype had taken extreme measures to obfuscate the program's traffic and functioning.[146] Several media sources reported that at a meeting about the "Lawful interception of IP based services" held on 25 June 2008, high-ranking unnamed officials at the Austrian interior ministry said that they could listen in on Skype conversations without problems. The Austrian public broadcasting service ORF, citing minutes from the meeting, reported that "the Austrian police are able to listen in on Skype connections". Skype declined to comment on the reports.[147][148] One easily demonstrated method of monitoring was to set up two computers with the same Skype user ID and password. When a message was typed or a call was received on one computer, the second computer duplicated the audio and text. This required knowledge of the user ID and password.

The United States Federal Communications Commission (FCC) has interpreted the Communications Assistance for Law Enforcement Act (CALEA) as requiring digital phone networks to allow wiretapping if authorized by an FBI warrant, in the same way as other phone services. In February 2009, Skype said that, not being a telephone company owning phone lines, it is exempt from CALEA and similar laws, which regulate US phone companies, and it is not clear whether Skype could support wiretapping even if it wanted to.[149] According to the ACLU, the Act is inconsistent with the original intent of the Fourth Amendment to the U.S. Constitution;[150] more recently, the ACLU has expressed concern that the FCC interpretation of the Act is incorrect.[151][152] It has been suggested that Microsoft made changes to Skype's infrastructure to ease various wiretapping requirements;[153] however, Skype denies the claims.[154]

Sometime before Skype was sold in 2009, the company had started Project Chess, a program to explore legal and technical ways to easily share calls with intelligence agencies and law enforcement.[155]

On 20 February 2009, the European Union's Eurojust agency announced that the Italian Desk at Eurojust would "play a key role in the coordination and cooperation of the investigations on the use of internet telephony systems (VoIP), such as 'Skype'. [...] The purpose of Eurojust's coordination role is to overcome the technical and judicial obstacles to the interception of internet telephony systems, taking into account the various data protection rules and civil rights."[156]

In November 2010, a flaw was disclosed to Skype that showed how computer crackers could secretly track any user's IP address.[157] Due to Skype's peer-to-peer nature, this was a difficult issue to address, but this bug was eventually remedied in a 2016 update.[158]

In 2012, Skype introduced automatic updates to better protect users from security risks, but received some challenge from users of the Mac product, as the updates cannot be disabled from version 5.6 on,[159] both on Mac OS and Windows versions, although in the latter, and only from version 5.9 on, automatic updating can be turned off in certain cases.[160]

According to a 2012 Washington Post article, Skype "has expanded its cooperation with law enforcement authorities to make online chats and other user information available to police"; the article additionally mentions that Skype made changes to allow authorities access to addresses and credit card numbers.[161]

In November 2012, Skype was reported to have handed over user data of a pro-WikiLeaks activist to Dallas, Texas-based private security company iSIGHT Partners without a warrant or court order. The alleged handover would be a breach of Skype's privacy policy. Skype responded with a statement that it launched an internal investigation to probe the breach of user data privacy.[162]

On 13 November 2012, a Russian user published a flaw in Skype's security that allowed any person to take over a Skype account knowing only the victim's email by following seven steps.[163][164] This vulnerability was claimed to exist for months and existed for more than 12 hours after being published widely.

On 14 May 2013, it was documented that a URL sent via a Skype instant messaging session was usurped by the Skype service and subsequently used in a HTTP HEAD query originating from an IP address registered to Microsoft in Redmond (the IP address used was 65.52.100.214). The Microsoft query used the full URL supplied in the IM conversation and was generated by a previously undocumented security service.[165] Security experts speculate that the action was triggered by a technology similar to Microsoft's SmartScreen Filter used in its browsers.[166]

The 2013 mass surveillance disclosures revealed that agencies such as the NSA and the FBI have the ability to eavesdrop on Skype, including the monitoring and storage of text and video calls and file transfers.[167][168][169] The PRISM surveillance program, which requires FISA court authorization, reportedly has allowed the NSA unfettered access to its data center supernodes. According to the leaked documents, integration work began in November 2010, but it was not until February 2011 that the company was served with a directive to comply signed by the attorney general,[167] with NSA documents showing that collection began on 31 March 2011.[170]

On 10 November 2014, Skype scored 1 out of 7 points on the Electronic Frontier Foundation's secure messaging scorecard. Skype received a point for encryption during transit but lost points because communications are not encrypted with a key the provider does not have access to (i.e., the communications are not end-to-end encrypted), users cannot verify contacts' identities, past messages are not secure if the encryption keys are stolen (i.e., the service does not provide forward secrecy), the code is not open to independent review (i.e., not available to merely view, nor under a free-software license), the security design is not properly documented, and there has not been a recent independent security audit.[171][172][173] AIM, BlackBerry Messenger, Ebuddy XMS, Hushmail, Kik Messenger, Viber, and Yahoo Messenger also scored 1 out of 7 points.[171]

As of August 2018, Skype now supported end-to-end encryption across all platforms.[174]

Cybercrime on application

Cybersex trafficking had occurred on Skype[175][176][177][178] and other videoconferencing applications.[179] According to the Australian Federal Police, overseas pedophiles were directing child sex abuse using its live streaming services.[180][178]

Service in the People's Republic of China

Since September 2007, users in China trying to download the Skype software client had been redirected to the site of TOM Online, a joint venture between a Chinese wireless operator and Skype, from which a modified Chinese version could be downloaded. The TOM client participated in China's system of Internet censorship, monitoring text messages between Skype users in China as well as messages exchanged with users outside the country.[181][182] Niklas Zennström, then chief executive of Skype, told reporters that TOM "had implemented a text filter, which is what everyone else in that market is doing. Those are the regulations." He also stated, "One thing that's certain is that those things are in no way jeopardising the privacy or the security of any of the users."[183]

In October 2008, it was reported that TOM had been saving the full message contents of some Skype text conversations on its servers, apparently focusing on conversations containing political issues such as Tibet, Falun Gong, Taiwan independence, and the Chinese Communist Party. The saved messages contain personally identifiable information about the message senders and recipients, including IP addresses, usernames, landline phone numbers, and the entire content of the text messages, including the time and date of each message. Information about Skype users outside China who were communicating with a TOM-Skype user was also saved. A server misconfiguration made these log files accessible to the public for a time.[182][184][185]

Research on the TOM-Skype venture has revealed information about blacklisted keyword checks, allowing censorship and surveillance of its users. The partnership had received much criticism for the latter. Microsoft remained unavailable for comment on the issue.[186]

According to reports from the advocacy group Great Fire, Microsoft had modified censorship restrictions and ensured encryption of all user information.[186] Furthermore, Microsoft partnered with Guangming Founder (GMF) in China.[187]

All attempts to visit the official Skype web page from mainland China redirected the user to skype.gmw.cn. The Linux version of Skype was unavailable.

Localization

Skype came bundled with the following locales and languages: Arabic, Bulgarian, Catalan, Chinese (Traditional and Simplified), Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hebrew, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Nepali, Norwegian, Polish, Portuguese (Brazilian and European), Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swedish, Thai, Turkish, Ukrainian, and Vietnamese.

As the Windows desktop program offered users the option of creating new language files, at least 80 other (full or partial) localizations were also available for many languages.[188]

Customer service

In January 2010, Skype rescinded its policy of seizing funds in Skype accounts that have been inactive (no paid call) for 180 days. This was in settlement of a class-action lawsuit.[189] The company also paid up to US$4 to persons who opted into the action.

Skype provided support through their web support portal, support community, @skypesupport on Twitter, and Skype Facebook page. Direct contact via email and live chat was available through their web support portal. Chat Support was a premium feature available to Skype Premium and some other paid users.

Skype's refund policy stated that they would provide refunds in full if customers had used less than €1 of their Skype Credit. "Upon a duly submitted request, Skype will refund you on a pro-rata basis for the unused period of a Product."

Skype had come under some criticism from users for the inability to completely close accounts. Users not wanting to continue using Skype could make their account inactive by deleting all personal information, except for the username.[190]

Due to an outage on 21 September 2015 that affected several users in New Zealand, Australia, and other countries, Skype decided to compensate their customers with 20 minutes of free calls to over 60 landline and 8 mobile phone destinations.[191]

Educational use

Although Skype was a commercial product, it was reported in 2011 that its non-paid version was being used with increasing frequency among teachers, schools, and charities interested in global education projects.[192] A popular use case was to facilitate language learning through conversations that alternate between each participant's native language.[193][194][195][196]

The video conferencing aspect of the software had been praised for its ability to connect students who speak different languages, facilitate virtual field trips, and engage directly with experts.[197][198]

Skype in the classroom was another free-of-charge tool that Skype had set up on its website, designed to encourage teachers to make their classrooms more interactive, and collaborate with other teachers around the world. There were various Skype lessons in which students could participate. Teachers could also use a search tool and find experts in a particular field.[199] The educational program Skype a Scientist, set up by biologist Sarah McAnulty in 2017, had in two years connected 14,312 classrooms with over 7,000 volunteer scientists.[200]

However, Skype was not adopted universally; some educational institutions in the United States and Europe were blocking the application from their networks.[201][202]
