Television came to Arizona on December 4, 1949 when KPHO-TV Channel 5 came on the air. There wasn't much programming in the early days but KPHO-TV carried programs from all 4 networks of the time (CBS, NBC, ABC, and DuMont) on kinescope (there was no live network connection to the western US until 1951), plus lots of local programming. 36 different channels have been used, including full-powered NTSC, LPTV, and digital stations.
