ITV was born out of the Television Act of 1954, which sought to break up the BBC's monopoly on British television and provide it with a commercial competitor, supported by advertising. ITV broadcast for the first time 60 years ago today, 22 September 1955. The first advert, shown at 8.12pm local time, was for Gibbs SR toothpaste. Take a look back at some images from the archives showing ITV's most notable moments.
