DWLS

DZXX (1955–1972; 1973-1976)

It first aired in 1955, when "Uncle Bob" Stewart opened the DZXX-AM 890 kHz station, the first pop music station in the country on AM format.

WLS-FM/The Giant (1976–1992)

On July 1976, GMA launched 97.1 WLS-FM as an adult standards and jazz station. In 1981, at the height of popularity of pop music it switched to Adult Top 40 format, with the slogan The Best Music. It was known for playing hourly Beatles music every weekday early mornings, which was later on adopted by 100.3 RJFM. In November 1988, upon the completion of GMA's Tower of Power, WLS earned the brand, The Giant 97.1 WLS-FM.

Campus Radio (1992–2007)

When GMA was renamed as the "Rainbow Satellite Network" in the early 1992, the station was reformatted on April 30, 1992 as Campus Radio 97.1 WLS-FM, with a Top 40 format. This was to target teens & early adults. Its notable programs were the longest-running program on the station, the legendary "Top 20 at 12" (anchored by Milo Cavarlez aka The Triggerman, which was first heard on Kiss FM 101.1 (now 101.1 Yes The Best), where the top 20 songs of the day were counted down in the mold of BBC Radio 1's The Official Chart Show at noontime, and "Campus Aircheck", an institution of sorts for aspiring DJs to get hired by Campus Radio, touted as "the first school on the air".

In 1995, when Mike Enriquez took over the radio operations, Campus Radio was reformatted to a contemporary MOR format, earning its slogan "Forever!". At this time, a few programs were introduced, notably the Message Center, wherein one's message must not be a greeting. By the end of 1999, it shifted back to Top 40.

Barangay LS (2007–present)

On February 14, 2007, Campus Radio rebranded as Barangay LS 97.1, using its old slogan, "Forever!". It reverts back to a masa format. Despite Campus Radio's dominant ratings performance in the pop category, GMA's FM radio sales unit failed to sell the format. With consistently low sales figures, this paved the way for Mike Enriquez to successfully persuade the network's upper management to agree to shift WLS to a seemingly more profitable "masa" format. Most of the staff were retained, albeit changing their names. Unfortunately, industry reception is lukewarm and Barangay LS has yet to regain the revenue losses incurred by the shift of advertisers to competing FM stations.

Last January 16, 2008 at around 6 pm, the station launched its new tagline, "Ayos!", which is also the tagline for RGMA's provincial Campus Radio stations. That same day, almost all of the staff who were also from the former Campus Radio format, and after years of loyal service to the GMA Network, were summarily dismissed by Mike Enriquez. Despite rising from #7 to #4 in the ratings, Enriquez deemed them unfit to take the format to the ratings game. In turn, they were replaced unceremoniously by jocks from RGMA provincial radio stations as well as jocks from other masa stations.

On January 17, 2011, facing competition with the latest masa stations, the new tagline "Tugstugan Na!" was launched and the station adapted the "crazy fun" sound brand in the market. Mike Enriquez was replaced by Glenn F. Allona as program director/station manager, aiming Barangay LS to bring back the focus on the staple of FM Programming which is music.

On February 17, 2014, Barangay LS 97.1 was rebranded with reformatted programs, new jingle, a new logo & a new slogan called "Isang Bansa, Isang Barangay". Also, 15 Barangay FM radio stations owned by Radio GMA formerly named as Campus Radio (including 99.5 RT for Cebu, 103.5 Wow FM for Davao and Super Radyo DYRU 92.9 for Kalibo) finally adopted the Barangay FM branding (and DYRU was added its music format to its station aside from news & public affairs format to pave way for station's reformat; along with other FM stations). The network rebranding was made to compete with its rival FM radio network My Only Radio, owned by the network's competitor ABS-CBN, following the relaunch of DWRR-FM as MOR's flagship station seven months earlier (July 8, 2013). Following the relaunch, a TV commercial of Barangay FM featuring Alden Richards, Pauleen Luna and Ryzza Mae Dizon was launched on March 24, 2014.^[3]
