Here is the classic TV commercial from the 1960’s for a Slinky. I think the main thing that has changed over the last 50 years in television is the use of a good-old jingle. Apparently, Slinky’s jingle featured the recording of a Slinky walking down the stairs. It’s hard to hear, but I can get the feel through the rhythm of the song.
