national superstations and additional regional out-of-market independents. The following day (July 23), television station owner Malrite Broadcasting (later Malrite Communications) filed a lawsuit in United States Court of Appeals for the Eastern District of New York to stop the rules from going into effect. The National Association of Broadcasters and Field Communications subsequently filed stay motions to the FCC (which denied the requests) until the Malrite suit was adjudicated, amid concerns over harm that the repeal could incur to station revenue and local viewership of syndicated programs if the same program could be duplicated by superstations and other distant signals. On June 19, 1981, the three-judge New York Court of Appeals panel unanimously affirmed the distant signal and syndication exclusivity repeals; after multiple delays, the repeal of both regulations went into effect one week later on June 24. The U.S. Supreme Court also affirmed the repeal by declining a request by the NAB to review the FCC order in January 1982. Interpretations of the copyright act also led to legal cases against superstation distributors. In April 1981, Tribune Broadcasting filed a copyright infringement suit against United Video in the United States District Court for the Northern District of Illinois, on grounds that United inserted teletext content from its Dow Jones business news service over the satellite feed's vertical blanking interval (VBI) during retransmissions of WGN's newscasts and other local programs in place of the teletext listings data that the station was relaying to United's Electronic Program Guide (EPG) service (later Prevue Guide and now the entertainment-based Pop) in violation of the Copyright Act's passive carrier rules. In October 1981, District Court Judge Susan Getzendanner denied an injunction to WGN Continental Broadcasting and dismissed the United Video case, determining that United was not required to carry the station's teletext transmission. The U.S. Court of Appeals for the Northern District of Illinois disagreed, ruling in August 1982 that United Video must retransmit WGN-TV's VBI teletext where directly related to and part of the 9:00 p.m. news simulcast, noting that United had no grounds to claim the unseen teletext exempted it from copyright liability as the Copyright Act's definition of what constitutes as a public performance was broad enough to encompass indirect transmission through cable affiliates.
