DWLS

1976–1992: WLS FM/The Giant

The station first went on air in July 1976 as 97.1 WLS FM, airing adult standards and jazz. In 1981, it switched to an Adult Top 40 format with the slogan "The Best Music", featuring hourly Beatles music on weekday mornings, a tradition later adopted by 100.3 RJFM. In November 1988, after completing GMA's Tower of Power, it rebranded as The Giant 97.1 WLS FM.

1992–2007: Campus Radio

On January 6, 1992, the station relaunched as Campus Radio 97.1 WLS FM with a Top 40 format targeting teens and young adults. Its flagship show, "Top 20 at 12" hosted by Milo Cavarlez ("The Triggerman"), counted down the day’s top 20 songs, inspired by BBC Radio 1's Official Chart Show.

Campus Radio also introduced "Campus Aircheck," a pioneering on-air program that served as a training ground for aspiring DJs to get hired.

In 1994, after Mike Enriquez took over GMA's radio operations, Campus Radio shifted to a mass-based format with the slogan "Forever!" and introduced programs like "Message Center," competing with Kool 106's Pager 106.^{[citation needed]}. By 2000, DWLS returned to Top 40, using custom jingles from JAM Creative Productions, originally made for Chicago’s WLS-AM.^[3]

2007–present: Barangay LS

On February 14, 2007, Campus Radio rebranded as Barangay LS 97.1, revived its old slogan "Forever!" and shifted back to a mass-based format. Despite strong pop ratings, the change was driven by persistent low ad revenue, prompting Mike Enriquez to push for a more commercially viable approach. Most staff stayed, adopting Filipino on-air names and language. However, the revamp drew criticism from loyal listeners, and by January 2008, the station had yet to recover advertising losses.^[4][5]

On January 16, 2008, at 6 PM PHT, the station launched its new tagline, "Ayos!" ("Okay!"), which was also adopted by RGMA's provincial Campus Radio stations. On the same day, nearly all staff from the former Campus Radio format were abruptly dismissed by Mike Enriquez, despite their years of loyal service to GMA Network. Although the station had improved its ratings from #7 to #4, Enriquez believed the existing team lacked the edge to compete further in the current format. They were unceremoniously replaced by on-air talents from RGMA’s provincial stations and former jocks from various networks.^[6]

On March 23, 2008, the former Campus Radio staff moved to 99.5 FM and launched Campus 99.5. However, the format ended on August 14 due to management and sales issues.

On January 17, 2011, Barangay LS introduced a new tagline, "Tugstugan Na!" (“Let’s jam!”), and adopted a “crazy fun” branding to refresh its image. Around the same time, Glenn F. Allona replaced Mike Enriquez as program director and station manager, steering the station back toward a music-driven format, revitalizing its core focus on dynamic, high-energy programming centered on music.

On February 17, 2014, Barangay LS underwent a major revamp with new programs, a jingle, logo, and the slogan "Isang Bansa, Isang Barangay" (“One Nation, One Barangay”). RGMA’s regional FM stations nationwide, including 99.5 RT in Cebu, 103.5 Wow FM in Davao and Super Radyo DYRU 92.9 in Kalibo, also rebranded under the Barangay FM name.^[7]

In July 2019, the station revived its original slogan, "Forever!". To mark the occasion, a new station jingle titled "Tayo ay Forever" was released, performed by GMA artists Ken Chan and Rita Daniela under GMA Music.^[8]

On March 20, 2020, Barangay LS 97.1 scaled down operations and began simulcasting with Super Radyo DZBB due to the COVID-19 enhanced community quarantine. Full programming and staffing resumed in early 2022 after the simulcast ended, except during their overnight hours with Golden Memories.

On April 5, 2026, most of its regional stations adapted the Barangay LS branding.
