Ptisi & Diastima

Ptisi & Diastima, whose Greek title Πτήση & Διάστημα translates approximately as “Flight & Space,” was a Greek specialist magazine focused on aviation, defence, and space. Its first issue appeared in November 1979, establishing the publication as the oldest aviation and defence magazine in Greece according to the cited reference material. The magazine served a specialist readership interested in military and civil aviation, aerospace developments, defence equipment, and related strategic subjects, although the available reference material does not provide a complete editorial or product catalogue. The publication was founded by Costas Cavvathas and initially issued by his company, Technical Press. This publishing relationship continued until 2006, when Technical Press was sold to Liberis Publications. The change in corporate ownership also marked the end of Cavvathas’s direct association with the magazine. Ptisi & Diastima continued publication under the new ownership, demonstrating that the title had an identity and readership distinct from its original founder. Liberis Publications subsequently sold the publication title to Faithon Karaiossifidis. Karaiossifidis is identified in the reference material as the later publisher and owner associated with the magazine. Circulation or readership figures cited for the title indicate a monthly readership of approximately 36,000 in 2006 and 44,000 in 2007. These figures suggest that the magazine retained or increased its audience during the period surrounding the ownership transition, although the available sources do not explain the methodology or whether the figures represent paid circulation, readership, or another audience measure. The title remained in use through the May 2020 issue. In June 2020, the current publisher changed the publication’s name from Ptisi & Diastima to Ptisi, making the May 2020 edition the final issue published under the original name. The brand is therefore best treated as a discontinued magazine title rather than an active standalone publication brand. The successor title may have continued the publication’s editorial activity, but the supplied reference does not establish its subsequent ownership, publishing schedule, or current status.

Ptisi & Diastima was established in Greece in 1979 by Costas Cavvathas. Its first issue was published in November of that year. The title’s name, Πτήση & Διάστημα, refers to “Flight & Space,” reflecting its editorial focus on aviation, aerospace, and defence subjects. It developed as a specialist monthly magazine rather than a general-interest publication and became associated with coverage of the aviation and defence fields in the Greek market. The magazine was published by Technical Press, Cavvathas’s publishing company, from its launch through 2006. The title’s longevity made it a notable publication within Greek aviation and defence media. The available reference identifies it as the oldest aviation and defence magazine in Greece, although it does not provide a detailed account of its editorial staff, contributors, distribution network, or individual issues. A significant ownership change occurred in 2006, when Technical Press was sold to Liberis Publications. Ptisi & Diastima continued after the transaction, but without its founder. This marked a separation between the magazine and the publishing company that had launched it. The reference material records monthly readership of 36,000 in 2006 and 44,000 in 2007. These figures indicate that the title maintained a substantial specialist audience during the post-sale period, but the cited material does not specify whether the figures describe audited circulation, readership estimates, or another audience measurement. Liberis Publications later sold the magazine title to Faithon Karaiossifidis, who is identified as the subsequent publisher and owner. The title continued under this ownership for the remainder of its original-name period. No reliable details are supplied here about later corporate structure, editorial changes, print production, or digital publishing, so those aspects remain undocumented in this entry. The final phase of the original brand occurred in 2020. In June of that year, Karaiossifidis changed the publication’s name to Ptisi. The May 2020 issue was the final issue released as Ptisi & Diastima. Accordingly, Ptisi & Diastima is recorded as a defunct magazine brand, while Ptisi represents the renamed continuation identified by the available source. The supplied evidence does not establish whether the renamed publication remains active or how closely its editorial scope corresponds to the earlier title.
