Article: In the early years of coverage the BBC had exclusive radio coverage with a picture of the pitch marked in the Radio Times with numbered squares to help the listener follow the match on the radio. The first FA Cup Final on Radio was in 1926 between Bolton Wanderers and Manchester City but this was only broadcast in Manchester, the first national final on BBC Radio was between Arsenal and Cardiff in 1927. The first final on BBC Television was in 1937 in a match which featured Sunderland and Preston North End but this was not televised in full. The following season's final between Preston and Huddersfield was covered in full by the BBC. When ITV was formed in 1955 they shared final coverage with the BBC in one of the only club matches shown live on television, during the 1970s and 1980s coverage became more elaborate with BBC and ITV trying to steal viewers from the others by starting coverage earlier and earlier some starting as early as 9 a.m. which was six hours before kick off. Nowadays, this continues with Setanta and ESPN having all-day broadcasts from Wembley, but terrestrial TV coverage usually begins two hours before kick off. The sharing of rights between BBC and ITV continued from 1955 to 1988, when ITV lost coverage to the new Sports Channel which later became Sky Sports.
