The media of Panama has been highly influenced by that of the United States, since the construction of the Panama Canal. Radio broadcasting in Panama began in 1922, and television broadcasting in 1956. Radio and television broadcasts also reached the Panama Canal Zone because it lay within the vicinity of Panama. A famous military broadcast network, the Southern Command Network (SCN), broadcast in Panama until the United States withdrew from the canal in 1999. The SCN remained on the air for hours during the invasion of Panama by U.S. troops in 1989. Color television in Panama is provided by the NTSC system.
