How was a British educational television show created by Jack Hargreaves. Made in Southern's Southampton studios, it provided answers to questions beginning with the word "How". Topics commonly covered included science, history, mathematics and simple puzzles. The formula proved so successful that it was soon broadcast to the whole ITV network and given two slots per week. The show was originally presented by Hargreaves alone. He was joined by Fred Dinenage, Jon Miller , Bunty James, Dr Tom Gaskell, Jill Graham and Marian Davies.
