KTFM was originally a move-in, where in 1991 it had a Tejano format as KRIO, KRIO started out as a Texas Music Station then flipped to Country. The country format was short-lived and lasted no longer than 8 months. This was during the Gillespie Broadcasting days which had a LMA with KONO-AM-FM. but by September 1998 they would flip to Regional Mexican as KLEY. On January 7, 2005, BMP would revive the KTFM calls after it acquired KLEY from Spanish Broadcasting System. When KTFM was revived, its name was "Jammin' 94.1" and its focus was on Rhythmic Oldies. But as the station struggled to get ratings, KTFM shifted to a Rhythmic AC direction by adding more current product and putting less emphasis on older material to keep up with the changing musical taste along with the 25-44 and Hispanic demographics KTFM targets in the San Antonio radio market. By November 2008 KTFM began shifting to a Rhythmic contemporary direction and was added to the BDS Top 40/Rhythmic reporting panel. In February 2009, KTFM tweaked the format and started broadcasting a Hot AC format. For many years, the call sign "KTFM" was at 102.7 under the name "FM 103 The New KTFM", "KTFM 103", "Hot 103 KTFM", and "102.7 KTFM", where it was first an automated pop station, then album rock, them various flavors of Top 40 including an Urban AC-leaning version of Top 40 trying to top then-rival KSJL's numbers, then to a Rhythmic/Freestyle-leaning Top 40, and then back to rock. Today, 102.7 carries the adult hits format "Jack FM" and uses the call letters KJXK. By April 2010, BMP flipped KTFM to Top 40/CHR, with a heavy emphasis on Dance crossovers. On January 7, 2016, at 9 a.m., following "Blondie & Nugget in the Morning",, KTFM began stunting as "94.1 El Taco," giving away free tacos at various locations around San Antonio, playing the Parry Gipp novelty song "It's Raining Tacos" on a loop, and its website emitting a green lightning strike with the word "Energize." At 4 p.m. that same day, KJXK began stunting with country music, leading listeners and rivals to believe KTFM was moving back to 102.7; at the same time as KTFM's relaunch, the stunt on 102.7 was revealed to be a publicity stunt. At 5 p.m., KTFM transitioned back to Rhythmic Top 40 and relaunched as "Energy 94.1", with the first song being "Sorry" by Justin Bieber. The rebranding was done to emphasize its Rhythmic/Dance-focused presentation of current hits and club mixes featuring local talent, as well as distinguishing themselves from KBBT and KXXM whose ratings are higher than KTFM's, but does consistently well. On February 23, 2016, "Blondie & Nugget in the Morning" were released from the station and replaced by the nationally syndicated radio show "Brooke & Jubal in the Morning". The show started airing on KTFM on March 1, 2016. On August 1, 2016, nationally syndicated "Tino Chochino Radio" was added as a show that runs on weeknights. On August 20, 2018, "The Dana Cortez Show", hosted by Dana Cortez and Anthony Almanzar, began airing on KTFM after transferring from Top 40/CHR rival KBBT, as the show became syndicated by ABC Radio. By July 2019, KTFM shifted back to a more mainstream Top 40/CHR.
KTFM-HD2 and K277CX 103.3
On February 10, 2015, KTFM launched an alternative rock format on its HD2 sub channel, branded as "103.3 The App", relayed on translator K277CX in Terrell Wells. The first song on "The App" was "Take Me to Church" by Hozier. The station was named "The App" because it heavily promoted listeners to download the app from iTunes and/or Google Play due to the station's weak signal over San Antonio, in addition to the lack of HD radios. Throughout the month of February and March, "The App" started off with 10,000 songs in a row, with a blend of 90's and 2000's rock and alternative mixed with today's alternative but tends to be more indie rock leaning. Eventually, the station began airing short commercial breaks and promoted concerts, such as the Maverick Music Festival and Vans Warped Tour, and bands such as Smashing Pumpkins, Awolnation, Falling in Reverse, and Breaking Benjamin. By late 2015, the App has hosted concerts in the Alamo Lounge, owned and operated by Alpha Media, with bands such as Jimmy Eat World, Saint Motel, Blue October, Nothing But Thieves, Colours, and several local rock bands. By late April 2015, The App added one live personality, DJ Mighty Iris, and until May 2016, more personalities have been added such as REZ, Sam, and even a morning show hosted by Tony Cortez from Energy 94.1. On April 21, 2017, at 5 p.m., after playing "Steady, As She Goes" by The Raconteurs, KTFM-HD2/K277CX flipped to classic hip-hop as "G103.3". The flip comes as the ratings for the alternative rock format failed to attract listeners, posting a 0.8 in the March 2017 Nielsen Audio book. The first song on "G" was "Hypnotize" by The Notorious B.I.G. On June 1, 2020, KTFM-HD2/K277CX changed their format to rhythmic contemporary, branded as "WE 103.3".
