2 November – The first regular high-definition (then defined as at least 200 lines) BBC Television Service, based at Alexandra Palace in London, officially begins broadcasting (after test transmissions began in August). The service alternates on a weekly basis between Baird's 240-line mechanical system and the Marconi-EMI's 405-line all-electronic system. Programmes are broadcast daily, Monday to Saturday from 3pm to 4pm and 9pm to 10pm. Leslie Mitchell is the first announcer to be heard on the new service.
By this year there are approximately 2,000 televisions worldwide.
