I have heard various technologies compared to color TV for purposes of creating a marketing campaign. The first color television broadcasting began in December of 1953, the Rose parade was televised in color on January 1st, 1954.
The first consumer color television rolled off the line in Bloomington Indiana at the RCA plant March 25th 1954. There were other earlier competitors but mostly because of the cost none were mass marketed; RCA sold 5,000 the first year at a cost of about $1000.
