Winky Dink & You

Winky Dink and You was a CBS children's television show that aired from 1953 to 1957, on Saturday mornings at 10:30 a.m. Eastern / 9:30 Central. It was hosted by Jack Barry and featured the exploits of a cartoon character named Winky Dink (voiced by Mae Questel) and his dog Woofer, with sound effects provided by Joseph Scholnick. Winky Dink and You created by Harry Prichett, Sr. and Ed Wyckoff, featured Barry and his sidekick, the incompetent Mr Bungle (Dayton Allen), introducing clips of Winky Dink, noted for his plaid pants, tousled hair, and large eyes.

  Praised by Microsoft mogul Bill Gates as "the first interactive TV show", the show's central gimmick was the use of a "magic drawing screen", which was a large piece of vinyl plastic that stuck to the television screen via static electricity. A kit containing the screen and various Winky Dink crayons could be purchased for 50 cents. At a climactic scene in every Winky Dink short, Winky would arrive upon a scene that contained a “connect the dots” picture. He would then prompt the children at home to complete the picture, and the finished result would help him continue the story. Examples include drawing a bridge to cross a river, an axe to chop down a tree, or a cage to trap a dangerous lion.

Another use of the interactive screen was to decode messages. An image would be displayed, showing only the vertical lines of the letters of the secret message, which viewers at home would quickly trace onto their magic screen. A second image would then display the horizontal lines, completing the text.

A final use of the screen was to create the outline of a character with whom Jack Barry would have a conversation. It would seem meaningless to viewers without the screen, further encouraging its purchase.
