Password (Daytime original run)
I'm guessing this commercial is in the middle of the jump cut from Lee Vines saying "Yes! It's Password!" to him saying "Now here's your host on Password, Allen Ludden!" in the GSN/BUZZR airings?
Not on the daytime airings. They would always have a simple billboard for whatever product was in the first spot, and then they would do intros, the first minute of ads, then start gameplay. Buzzr has edited these shows so seamlessly that the casual viewer would never suspect otherwise.
Often on the nighttime show, they would do the first commercial before Allen was introduced, then intros and start gameplay.
