From 73 onwards, Price is Right, Match Game and Tattletales filled the 3pm hour at various times. Both Price and Match Game got moved to the mornings and All in the Family was brought in at 3 to tackle AW on NBC.
Then GL expanded which pushed Family back to 3.30.When AITF went into syndication MASH was brought in.
Finally GL took over from 3-4.
So for about 5 years CBS offered alternative to soaps at 3pm.
