NEW YORK — In the century since its official founding on October 18, 1922, the British Broadcasting Corporation (BBC) has documented scores of historical moments, from the 1982 Falklands war to the 1953 coronation of Queen Elizabeth II in Westminster Abbey. There have been royal weddings that riveted audiences locally and around the world as well as news stories on the changing face of Ireland and Scotland. Along the way, the BBC moved from exclusively broadcasting via radio to the world of television and, later, online entertainment. It has helped shape the culture with important early appearances by The Beatles and The Who to popular TV shows such as Fawlty Towers (which served as this writer’s introduction to BBC programming while growing up in New Jersey) and Doctor Who, which debuted more than 60 years ago and is going strong in its second incarnation.
