1968–1985: DZFX
The station first went on the air on May 31, 1968 under the call letters DZFX. The country's first stereo-multiplex FM radio station, it was under the ownership of Makati Broadcasting Network Corporation, owned by businessmen Tony and Bob Garcia and Adolfo Duarte. It played classical music and "elevator music" and non-commercial station 98.7 DZFE was its only competitor. On October 11, 1985, a few minutes before 12 noon, it bade goodbye with a Mozart piece.
1985–1989: Kiss FM
Shortly after DZFX 101.1's sign off on October 11, 1985, it was rebranded as Kiss FM 101.1 (call letters DWKS) with studios located at 14th floor of Insular Life Building at Ayala Avenue corner Paseo de Roxas, Makati, with "Dancing in the Streets" by Mick Jagger and David Bowie, as its first song played on the station. It introduced innovations like having the frequency number on its telephone number, programs like Top 20 at 12 and the launch date as 10–11, standing as the frequency. From 1985, it had the Contemporary Hit Radio format, competing directly with 99.5 RT (now 99.5 XFM Manila) and 97.1 WLS-FM (now Barangay LS 97.1). Singer Martin Nievera also worked with the station under his sobriquet "Mad Man" and had his program every Saturday afternoons.
1989–1995: Kiss Jazz
It changed its name to Kiss Jazz 101.1 and transformed into a smooth jazz format from June 1989 to December 1995 competing directly with Citylite 88.3 (now Jam 88.3) before it quietly went off the air.
1995–1998: Showbiz Tsismis
On December 18, 1995, Manila Broadcasting Company acquired 101.1 FM from Makati Broadcasting Network, launching 101.1 Showbiz Tsismis, the country's first FM station to blend show business gossip with music. Operating under the call sign DWST, which stood for "Showbiz Tsismis" (Showbiz Gossip), the station moved its studio to the FJE Building in Legazpi Village, Makati, integrating them with the existing DZRH facilities
101.1 Showbiz Tsismis distinguished itself by incorporating show business news reports delivered by reporters in a style similar to AM stations. It is also made history by being the first Philippine radio station to simulcast its programming via satellite.[3][4]
1998–present: Yes! FM/Yes! The Best
On December 6, 1998, 101.1 was re-launched as '''Yes! FM 101.1''' with new call letters DWYS. Shifting to a mass-based format, similar to its sister station 90.7 Love Radio it quickly became the undisputed number 1 FM station from 1999 to 2002.[5]
In July 2002, all Manila Broadcasting Company (MBC) stations relocated from the FJE Building in Makati to the Star City Complex in Pasay, Philippines.
In 2008, Yes! FM 101.1 underwent another repackaging, adopting the slogan "Automatic 'Yan!" (It's Automatic!). While its playlist closely mirrored that of 90.7 Love Radio, its overall programming maintained a distinct identity.
As part of the "Radyo? Dalawa Lang Yan!" campaign, launched by Yes! FM and Love Radio in early 2011, a significant DJ reshuffle occurred in 2012. Several DJs from 90.7 Love Radio including Rica Herra, Missy Hista, Rico Pañero and Lala Banderas moved to Yes! FM 101.1. In exchange, Diego Bandido, Emma Harot, Kristine Dera and Robin Sienna transferred to Love Radio. This shift also coincided with Yes! FM 101.1's new "Hayahay" branding, a slogan that was subsequently adopted by other Yes! FM, Hot FM, and Love Radio stations.
In 2014, Yes! FM was awarded the Gawad Tanglaw Hall of Fame award, having been awarded as the Best FM Station for five consecutive years.
On July 18, 2016, at 6:00 AM, the station rebranded as '''101.1 Yes! The Best''', adopting the new slogan, "The Millennials' Choice."
