that would allow programs to be selectively blacked out based on the media market would not likely be marketed until after the initial compulsory license expired in 1994 and that the expense of "preventing viewing by a relatively few authorized home satellite dish owners for a relatively short period" would be greater than that incurred by cable providers. Copyright laws pertaining to broadcast signal carriage by satellite providers were eventually overhauled through amendments to the Communications Act of 1996 that were added through the November 1999 implementation of the Satellite Home Viewer Improvement Act (SHVIA), which allowed satellite providers to carry local broadcast signals on the Congressionally-suggested condition that the FCC develop rules protecting the sports, network and syndicated programming rights of local broadcasters. On November 2, 2000, the FCC approved identical network non-duplication, syndication exclusivity and sports blackout rules applying to the six FCC-designated national superstations (WGN-TV, KTLA, WPIX, KWGN-TV, WSBK-TV and WWOR-TV) and, in the case of the sports blackouts, other distant signals retransmitted over home dish units to an extent where it would be "technically feasible and not economically prohibitive;" this statute would eventually limit distribution of the five grandfathered stations to rural areas without distributors of similar programming. The rules, which took effect on November 30 and also applied to satellite common carriers that uplinked and distributed the superstations, gave satellite providers at least four months to implement duplication protections for network and syndicated programs and 60 days notice to comply with sports and programming blackout requests. An exemption to the Communications Act's retransmission consent statute in the SHVIA rules allowed satellite carriers to retransmit a superstation signal absent the station's prior written consent under the latter two aspects of the aforementioned FCC-defined "national superstation" criteria, provided that the service complies with the non-duplication, syndication exclusivity and sports blackout rules. (TBS was not covered under the SHVIA's de facto distant signal grandfathering clause as its national feed was considered a technically separate entity from its over-the-air parent feed in Atlanta. The act's network non-duplication and Syndex rules were thought to negatively affect the distribution of WGN as its national feed was compliant with those restrictions.) The Satellite Home Viewer Extension and Reauthorization Act (SHVERA), signed into law on December 8, 2004, allowed satellite providers to carry "significantly viewed" superstations and distant network signals to subscribers royalty-free and with the payment of retransmission consent, provided that the
