When you think of 70s commercials, you can’t help but think of K-Tel.
Paraphrased from Wiki: Philip Kives formed K-Tel in 1968. He was a door to door salesman that sold products created by Seymour Popeil. (Seymour Popeil is the father of Ron Popeil, who in turn is the founder of Ronco. I found that interesting.) In 1965 Philip had sold one million of the “Feather Touch Knives” (which were produced by Seymour) in Australia within a five month period!
Of course after you have bought several of the K-Tel records you need something to hold them!
And don’t forget you have to keep them clean. Ronco to the rescue!
