Family Breeds Content

On August 3 Fox will air ''That '70s Show'' for the last time, marking the end of the Masterson brothers era on primetime TV.

Naturally, this event leads to the very simple question: What other siblings appeared as regular characters on different primetime TV shows at the same time?

I don't care about siblings playing different characters on the same show, like Tia & Tamera Mowry on ''Sister, Sister'' or the Olsen twins on ''Two of a Kind.'' And these family members had to be contemporaries — the Sagal sisters just missed since Katey appeared on ''Mary'' from 12/85 - 4/86 immediately after her sisters (Liz, Jean) played ''Double Trouble'' from 8/84 - 8/85.

Just get to the answer, you say? OK. OK. Here it is — the list of siblings who regularly appeared on different, contemporary primetime shows.
