aired on CBS the last season.:lol: I knew about Family Matters but had no clue that Step by Step was also moved to CBS. I found out because I was on youtube looking for ABC eps of Family Matters and came across a CBS block party promo for Family Matters and Step and Step below

Im surprised CBS bought the rights to both show at that time since all the kids was older

It was definitely a surprise at the time.
