Procter & Gamble had a good line of detergent products back in the day. They've sold off some brands (i.e. Oxydol), and retained others (Cheer, Tide, Gain). Somewhere in the middle is Bold, which P & G introduced sometime in the 50's or 60's. The Wikipedia page only says it debuted in the UK in 1974.
Anyway, Jo Anne Worley (Rowan & Martin's Laugh-In) sings the praises of the product in this 1968 ad.
