You just don't see these kind of commercials anymore (1965?)

 There was a time when Procter & Gamble arranged for their celebrity endorsers to interview real families to better promote their product.

One such example is this mid-60's offering with June Lockhart (Lost in Space, ex-Lassie) doing just that for Crest toothpaste. At the time, June was also hosting beauty pageants (Miss USA & Miss Universe) for CBS before the baton was passed to Bob Barker.

It's the human interest angle that drives spots like this. June spent a couple of years doing these ads, and Crest had a tradition of having celebrities doing ads, including Chuck Connors, and, after Lockhart, Arthur O'Connell (ex-The Second Hundred Years), the latter of which we've already seen as Mr. Goodwin, the kindly shopkeeper. June is still with us at 96, still going strong.
