While radio broadcasting was still in its infancy the marvel of television was already being developed. The first step towards its invention was taken in 1873 but the person responsible for developing it was John Logie Baird. In 1926 he gave the first demonstration of a television picture. As a home entertainment, television rapidly became more popular than any other form. A news broad cast b ecame more immediate when people could actually see the scene in question and the movements of the figures. Films could be viewed in the comfort of the home and variety shows were also available. One of the advantages of travel progarmmes was the glimpse of far – away places which many viewers would not o therwise have seen. Though much of the entertainment was of a popular kind like quiz competitions, some remarkable cultural programmes were also broadcast. Just as with radio in earlier days, the publicit y given to actors and actresses on the screen meant that a group of personalities became familiar in every household. One o f the most popular programmes was the televised coverage of sports and an interesting result of the television b roadcast was the increased attendance at the actual events. How far this was due to a growth in interest in the game and how far out of the spectators’ desire to appear on the screen is not clear
