The More You Know is a series of public service announcements (PSAs) broadcast on the NBC family of channels in the United States and other locations, featuring educational messages. These PSAs are broadcast occasionally during NBC's network programming.
The spots feature personalities from various NBC shows, as well as other notable figures such as U.S. presidents. Tom Brokaw was the first person to do The More You Know spot; it aired on NBC in September 1989, succeeding the One to Grow On PSAs that were used from 1983 to 1989.
The PSA series has become the most well-known in the United States and, like any popular series, has been the subject of many a parody.
