In 1954, the station began commercially as KSAN-TV on UHF channel 32; it was one of the first UHF TV stations in California. Owned by the Patterson family, operators of KSAN radio, the station was a small production studio and broadcast operation housed in the renovated Sutro Mansion in San Francisco and showed an amalgam of boxing and wrestling matches, medical conferences, and old movies. The station went off the air in 1958. The TV station was purchased by Metromedia in 1968, when the call sign was moved to an FM radio station and the TV station rechristened KNEW-TV, to match its co-owned KNEW radio and to complement Metromedia's flagship station in New York, WNEW-TV. KNEW-TV ran the syndicated Metromedia talk shows and variety programming of such stars as shock-talker Joe Pyne, and others. This format was unsuccessful, and by 1970, channel 32 was given to leading public broadcaster KQED and had its call sign changed again, this time as KQEC, a member station of the Public Broadcasting Service. KQED held onto the station until 1988 when the Federal Communications Commission revoked the license, ruling that it had been off the air too long to remain in the hands of the KQED ownership, and reassigned the license to Minority Television Project, one of the challengers of the KQEC license. In the FCC's 2016–2017 Broadcast Incentive Auction #1001, KMTP-TV successfully bid to go off the air for a compensation of $87,824,258. KMTP claimed in a March 31, 2017, press release, that it was negotiating with other broadcast stations in the Bay Area to share a channel. In FCC filings, it claimed a Channel Sharing Agreement had been signed, after completion of the auction, that would enable KMTP to continue broadcasting but on a different channel. This would be seamless for viewers as they would still tune to channel 32.
Controversy
In 2004, the FCC levied a $10,000 fine against KMTP for showing paid commercials on a station with an educational license. While it is commonplace for PBS and similar stations to show underwriters' messages that resemble commercials, it is illegal for educationally licensed stations, like KMTP, to show advertisements that do not meet the standards for underwriting announcements. KMTP appealed the decision in 2005, but the fine was upheld, prompting KMTP to file a lawsuit against the FCC in U.S. District Court the following year. In suing the FCC, KMTP felt it was unfairly penalized by the FCC's rules concerning underwriting that did not take into account foreign language broadcasting. The underwriting rules do not take into account foreign languages and the variations in pronunciations and meanings. KMTP carried out research to find out what the public interpreted a commercial to be. Using a numerical grading system, certain aspects of a video clip were found by the public to "feel" like a commercial or not like a commercial. These findings were presented to the FCC, as it did not depend on particular words or phrases which can be misinterpreted when foreign languages are used. The FCC rejected KMTP's attempt to clarify the underwriting rules, leaving KMTP with no choice but to take the matter to court. On April 12, 2012, the U.S. Ninth Circuit Court of Appeals ruled on two of the issues raised by KMTP's suit. The court ruled that noncommercial stations can air advertisements for both candidates and political position statements. The 1981 federal law was found to be violating free speech. This was a partial victory for KMTP, as it did not address the basic issue of how commercials differ from the sponsorships on which most public stations depend for financial support.
