XHITZ-FM, also known as Z90.3, is an English-language Top 40 radio station based in Tijuana, Mexico. It broadcasts to the San Diego-Tijuana radio market and is owned by Comunicación XERSA, S.A. de C.V. Local Media San Diego, an American company, holds 49% of the concession and programs the station. The studios in San Diego are home to two other Mexican FM stations. XHITZ-FM has an effective radiated power of 100,000 watts and abides by all Mexican broadcast regulations. It carries the Top 40/CHR version of "Sunday Night Slow Jams" and is one of two affiliates in the area for the program. XHIS-FM, owned by Califórmula Broadcasting, began broadcasting in September 1970 and received its concession in November 1973. It aired an automated progressive rock format called "HIS Radio" and was one of the first border blasters on FM. XHIS and its sister station XHERS were successful, with two of the top three stations in San Diego within six months. In 1973, Time Sales faced complaints from San Diego broadcasters about unfair competition from Mexican stations that didn't have to follow FCC rules. The FCC investigated Time Sales and as a result, they folded. The station was then operated under a new brand, "Estéreo 90, La Buena Onda", and played soul music and R&B. In 1981, a row and a strike led to the sale of XHIS and XHERS to Grupo Radio Centro. This marked GRC's first expansion outside of Mexico City. XHITZ-FM was originally an album-oriented rock station under the ownership of San Diego Radio Company until an ownership dispute led to the format being changed by Califórmula. The station went through multiple ownership changes before eventually flipping to a rock-oriented hits format called "Pirate Radio," which only lasted for a year. XHITZ-FM, also known as Z90, started as a dance-leaning Top 40 radio station in 1990. It quickly gained popularity and beat its competition, Q106. In 1993, XHITZ's success forced the market's only Urban Contemporary station, XHRM-FM, to change formats. Over the years, XHITZ evolved into a hip-hop leader before returning to its dance-leaning direction and eventually rebranding as "Jammin' Z90." Today, it airs a mainstream Top 40/CHR format.
