British network Sky Sports claims it will broadcast the world's first live sports event in 3-D when Arsenal hosts Manchester United in the Premier League Sunday. Previous 3-D trials have been limited to closed-circuit broadcasts in Britain and the United States, but the BSkyB channel will be transmitting Sunday's match via regular satellite decoder boxes to selected pubs in Britain and Ireland. Football fans will have to wear special glasses to watch the 3-D televisions at the nine venues as they preview Sky's dedicated 3-D channel, which will be launched in April. The channel will be available to pub subscribers before being expanded to regular customers and will initially broadcast one Premier League match a week in the new format. Viewers in the United States won't witness live sport in 3-D until June when ESPN broadcasts the World Cup, although – like in Britain – there have been trials of live sport in movie theaters.
