On November 30, 2006, NBC Universal (owner of rival KVEA, channel 52 and then-owner of KWHY, channel 22) filed a petition with the Federal Communications Commission (FCC) to deny KAZA's license renewal, on basis that TV Azteca controlled 51.6% of the station (above the FCC-designated 33% interest limit for foreign owned broadcasters) via loans and other interests. According to the "Los Angeles Times", it is believed to be the first challenge to a license renewal sent to the FCC since 1979 (notwithstanding the two-decade long RKO General license challenges including KHJ-TV that were not fully sorted until the late 1980s).
