San Antonio
Radio

About 50 radio stations can be heard in the San Antonio area; 30 of them are in the city proper. San Antonio is home to iHeartMedia, the largest operator of radio stations in the U.S. Its flagship, WOAI AM-1200, is known for its local news operation, considered among the best in the country. It is a 50,000-watt clear channel station that reaches most of North America at night. The first radio station to broadcast in South Texas was KTSA AM-550 in 1922.

The region's National Public Radio member is Texas Public Radio, a group of three stations; KSTX 89.1 FM is NPR news/talk, KPAC 88.3 is a 24-hour classical music station, and KTXI 90.1 is a mix of NPR news/talk and classical music broadcast for the West Central Texas Hill Country. KSTX also broadcasts "Riverwalk Jazz", featuring Jim Cullum Jazz Band at The Landing, a fixture on the River Walk since 1963.

KRTU 91.7 is a non-commercial radio station based at Trinity University. Unlike most other college radio stations in the U.S., the station plays jazz 17 hours a day and college rock/indie rock at night. College alternative station KSYM, 90.1 FM, is owned by the Alamo Community College District and operated by San Antonio College students; like KRTU, it plays the Third Coast music network during the day and alternative music at night.

Most Latin American stations in the area play regional Mexican, Tejano or contemporary pop. On January 12, 2006, Univision -owned KMYO-FM "La Kalle 95.1" changed its format from Hispanic-Rhythmic Contemporary Hits to Spanish Oldies, then named "Recuerdo 95.1". On November 10, 2006, Univision flipped KLTO Tejano 97.7's format to reggaeton in an attempt to reintroduce the format to San Antonio. Then 97.7 was flipped again to feature a rock format. The station no longer broadcasts anything in English. While still owned by Univision, it broadcast music by artists such as Linkin Park, before being sold to the Educational Media Foundation and flipping once again to Air1.

95.1 was then flipped back to the "La Kalle" format again after being flipped to feature a "95X" format. KLTO was acquired and is operated as a simulcast of KVBH-FM Vibe 107.5. San Antonio radio is diversified, due to an influx of non- Tejano Latinos, mostly from the East Coast, who serve in the city's various military bases, as well as immigrants from Mexico. Therefore, just like in the rest of the country, radio station conglomerates have been changing formats in San Antonio to reflect shifting demographics.
