The first sports event broadcast in the United Kingdom was a Rugby Union international between England and Wales, broadcast from Twickenham in January 1927. Two weeks later the first broadcast of a football match took place, with the BBC covering Arsenal's league fixture against Sheffield United at Highbury. Listeners to the broadcast could use numbered grids published in the Radio Times in order to ascertain in which area of the pitch (denoted as "squares") the action was taking place due to a second commentator reading out grid references during the match.
