 In 2005, the media criticism organization Fairness and Accuracy in Reporting (FAIR) released a study of C-SPAN's morning telephone call-in show "Washington Journal", showing that Republicans were favored as guests over Democrats by a two-to-one margin during a six-month period that year, and that people of color are underrepresented.A 2007 survey released by the think tank Center for Economic and Policy Research reported that C-SPAN covered conservative think tanks more than left-of-center think tanks.In 1992, Congress passed must-carry regulations, which required cable carriers to allocate spectrum to local broadcasters.
