They're know for distributing "news" stories and commentary to their stations to push their right wing agenda and most people don't even realize that the folksy reporter or commentator isn't local.
http://en.wikipedia.org/wiki/Sinclair_Broadcast_GroupSinclair had experimented with using a centralized news organization called News Central that provided prepackaged news segments for distribution to several of the group's stations. These segments were integrated into programming during local news broadcasts. Mark E. Hyman, a high-ranking executive at Sinclair, also created conservative editorial segments called "The Point" that were broadcast on all of the group's stations with news departments. In addition, most of the stations that aired News Central emulated the prepackaged news studio appearance for local stories. This model was ultimately unsuccessful, and on March 31, 2006, News Central ended its national news broadcasts (although the "Point" commentaries lasted until November 30, 2006). Most stations running the News Central format ended up cancelling their news coverage altogether, although some stations that did so have subsequently contracted with competing stations in their markets to produce their newscasts.
Sinclair still produces a one-minute national news briefing for its stations, entitled Washington Newsroom. Starting in 2007, Sinclair launched a new newscast on some of its' stations, completely separate from local news operations, called American Crossroads. Like News Central and "The Point", the program, hosted by Jeff Barnd (a news anchor at WBFF) covers national news stories and offers a conservative editorial segment.
