scrambled from the outset, using the Videocipher II encryption system as well as the second and third EMI-delivered superstations to be encrypted, after having converted the WWOR satellite signal to an encrypted format in March 1986. (Within two months of EMI making the station available via satellite, United Video assumed marketing rights for KTLA under a partnership with Eastern Microwave.) Both services had their distribution limited primarily to the home dish market, whereas their cable distribution remained confined to their respective regions (New England for WSBK and the Southwestern United States for KTLA). Unlike with WTCG/WTBS, Tribune Broadcasting (owners of WGN-TV, WPIX, KTLA and KWGN-TV until the completion of Tribune's purchase by Nexstar Media Group and concurring spin-off of WPIX to the E. W. Scripps Company in September 2019, with both successor parents inheriting the classification for those stations) and the various owners of WSBK (Gillett Communications, Paramount Stations Group and CBS Television Stations) have treated their satellite-delivered stations as "passive" superstations, opting to assert a neutral position over the relay of its signal by an intermediate common carrier to a national audience and leaving national promotional duties for multichannel television services and their subscribers to the satellite carriers that retransmitted their signals; in kind, neither station received direct compensation from United Video or EMI for retransmission or promotion of their signals but received royalty payments paid by carrier cable systems to the Copyright Royalty Tribunal (CRT) for their retransmission of programs that are copyrighted in the name of the individual stations and/or their respective parent companies. This benefited the stations as it allowed them to continue paying for syndicated programming and advertising at local rates rather than those comparable to other national networks. Even so, WGN would gradually switch to a more "active" stance in later years; Tribune began relaying the station's Chicago broadcast feed to United Video directly in 1985, and eventually acquired a majority stake in the rechristened TV Guide Inc.'s UVTV satellite unit in April 2001 as the company was spinning off its satellite carrier assets to focus on TV Guides magazine, direct-to-cable program listings and interactive program guide services. Tribune, as a whole, had also shifted from opposing satellite retransmission of its stations sans permission to weighing in the benefits of having its stations be distributed to a wide audience, to the point of being in strong opposition against the reimposition of the syndicated exclusivity
