Here are a series of commercials from the TV-12 (Erie, PA) NBC recorded in between Doctor Dean, Classic Concentration, Candid Camera, and A Closer Look sometime between July 1 and 3, 1992. There are lots of promos related to both Independence Day and the Summer Olympics in Barcelona, so this video is full of history.
