Did this opener presage the computer-screen era? OK, not really. But decades before 24, The Brady Bunch introduced its story with a moving tic-tac-toe board of a screen image that spoke to an era of increasingly broken-up and reconfigured families. And the way the actors looked at one another from their little boxes? Meta-cool. How convenient that there was a slot for Alice the housekeeper.
