Cooperative frequency coordination between both city regions is quite common; an example is XETV-TV 6, where the "K" being replaced by the "X" as an indicator that it is a Mexican-licensed station. The two other such TV stations are MyNetworkTV on XHDTV 49, and Miami-based (and NBC-owned) Telemundo on XHAS-TV 33. These stations will not be required to shut down their NTSC analog TV operations in June 2009, as full-powered FCC-licensed stations must. In 2007, a bill in the U.S. Congress called the DTV Border Fix Act was introduced, which would have allowed all stations in San Diego, and all television stations within of the Mexican border, to keep their analog signals active for another five years, delaying the television transition that the rest of the United States would be going through; while the bill passed the Senate, it did not pass the House.
