The Theater Television Network was an early American television network founded in 1951. The network wasn't a traditional 1950s television network: unlike the other TV networks that operated at that time, Theater Network programs weren't broadcast into homes; instead, they aired at participating movie theaters.
The Theater Television Network, like many current theaters do for major events, broadcast mostly sporting events: NCAA basketball games, boxing matches, entertainment events. TTN however also broadcast public affairs programming. The network broadcast Harry Truman's 1951 State of the Union address.
