ITV Studios also produces programmes for other UK broadcasters outside of its own network. These include the BBC, Channel 4, Channel 5 and Sky. ITV Studios is based in London and Manchester, with the centre in Leeds now only home to "Emmerdale" and Shiver Productions (formerly Yorkshire-Tyne Tees Television's then Granada Productions' northern features department). The production centres in Bristol and Norwich closed in 2006 and 2012 respectively. ITV Studios also owns So Television after acquiring Graham Norton's production company in 2012. On 22 April 2013, ITV announced they had acquired production company The Garden for £18 million; which is best known for producing Channel 4 series "24 Hours in A&E". In 2013, ITV launched a new production company named Potato. 2016 saw ITV Studios secure a four-year British horse racing deal which saw the Cheltenham Festival, Grand National and Royal Ascot all be shown on ITV.
