In the movie City Slickers, Billy Crystal's character claimed to have been a sales executive for the fictional station "WBLM Radio".

History

WBLM signed on the air on March 1, 1973 on 107.5 MHz. By day, it played Beautiful Music (also known as Easy Listening, mostly instrumental versions of Broadway, Hollywood and popular hits) with free-form progressive rock airing from 6 p.m. to 6 a.m. The station was licensed to Lewiston, Maine and its antenna was located in Litchfield, Maine, also the site of the original studio, which was a double-wide mobile home. Later that year, WBLM became a full-time progressive rocker. Given that the transmitter site was some 40 miles away from Portland, the station's signal was somewhat spotty in Portland and beyond. In 1979, it modified its format to mainstream album-oriented rock, after being challenged in the ratings by what at the time was a new 3,000-watt album rock station, 100.9 WLOB-FM, known as "FM 101" and currently WYNZ. On December 6, 1989 it switched frequencies with 102.9 WTHT. 102.9 was previously beautiful music station WGAN-FM from its sign-on in February 1967 until 1985. Prior to 1966, 102.9 was WLOB-FM, but not related to today's AM 1310 WLOB. The 107.5 frequency is now WFNK, ironically a direct competitor to WBLM with a classic rock/classic hits format. The two stations are often at the top of the Portland ratings list.

WBLM has a colorful connection to rock acts Frank Zappa and Captain Beefheart. WBLM's nickname is "The Rock and Roll Blimp". The stations on air catchphrase is: "It's The Blimp Frank it's The Blimp!"; both refer to the Captain Beefheart track off the album Trout Mask Replica "The Blimp", which is where the catchphrase comes from (the catchphrase is a portion of the beginning of that song). It's The Blimp "Frank" is in reference to Frank Zappa as the portion of the song used for the catchphrase is a recording of a phone call made from Beefheart's recording session back to their record label owner Frank Zappa about their new song titled "The Blimp". The "Cosmic Muffin" astrological forecast, which was a daily report on WBLM for years also used as its theme song "Muffin Man" by Frank Zappa, specifically the vocal portion proclaiming "The man thought he was a man but he was a muffin."
