Independent Television News has been the provider of national news to the ITV network since 1955, set up as a result of the 1954 Television Act.
The first ever broadcast was at 10pm on September 22 1955. The 24 year-old former athlete Christopher Chataway was the launch newscaster. The following year he was joined by Ludovic Kennedy and Huw Thomas.
Unlike the staid BBC newsreel, ITN soon established itself as a populist and enthusiastic service, with a journalistic style never seen before on British television. It's reporters - including Robin Day - were never afraid to ask searching questions, taking politicians totally by surprise. Even the signature tune had a spring in its step. "Non Stop" was used until as late as 1982, even after special compositions were made for "News at Ten" and "First Report".
