The Museum of Broadcast Communications is an American museum established in 1985 to collect, preserve, interpret and exhibit historic documentation from the fields of radio, television and broadcast advertising for use by broadcasters, students, scholars and the public. The Illinois-based nonprofit corporation owns and manages multiple subsidiaries, Museum.TV, The National Radio Hall of Fame, radiohof.org, The Encyclopedia of Television, The Encyclopedia of Radio, The Encyclopedia of Advertising and The Great Debate & Beyond. As well as having a long-established presence on the Internet, the Museum of Broadcast Communications is completing work on a 62,000-square-foot museum facility in downtown Chicago. For nearly 100 years, radio, television- and the internet- have entertained, informed and at times inspired us. Realizing its role in defining popular culture, the MBC will expand its commitment to examine and interpret the world of broadcasting through public programs, exhibitions, screenings, publications and access to its cast collection of important artifacts and nearly 100,000 hours of programming.
