Speaking of Zenith, just about anytime that you turn on a TV these days, any brand of TV, mind you, you see commercials extolling the virtues of new Chromacolor. It is touted as a "totally advanced color TV system, (the) first to fully-illuminate every color dot on a jet black background".

The Zenith "Eakins" model, seen here, is one of the new Chromacolor sets currently for sale at the Anchor Department Store. With one of these sets sitting in your living room, you could be tuning into programs such as "Rowan & Martin's Laugh-in", "The Carole Burnette Show", "To Rome With Love", "Room 222", "Love American Style", "The High Chaparral", "Ironside" and "The Mod Squad".
