One to Grow On is an educational public service announcement that broadcast during NBC's Saturday morning line-up from 1983 to 1989, when the network ran cartoons.

One to Grow On focused on ethical and personal safety dilemmas and attempted to teach viewers how to solve them.

The public service announcement appeared immediately after the end credits of NBC cartoons, such as ABC did with Schoolhouse Rock!

After the actors introduced themselves (which, until 1986, was followed by a 30-second commercial), live-action sequences followed, in which a child faced an ethical dilemma.

The segments were hosted by the stars of NBC primetime series, including from: Many of the celebrities featured were from NBC prime time programs that kids had been familiar with, parents being comfortable enough to allow kids to watch these programs, however, René Enríquez from the adult-oriented prime time show Hill Street Blues also hosted a segment specifically on how children should not be watching the show since it was broadcast too late, past a typical child's bedtime on a school night, as well as briefly evaluating it's more mature dramatic content compared to the other NBC programs.
