Two years after it was meant to go live, and with a list of backers that include*the BBC, ITV, Channel 4, Channel 5, Arqiva, BT and TalkTalk,**YouView today finally crashed the UK TV party. Available by the end of July with a selection of major retailers,*the service is based around an all-in-one set-top box that you can use without a subscription, which includes 100 digital TV and radio channels, catch-up and on-demand services, as well as the ability to record programs.But with a pricetag that will begin at £299 ($469) without the required broadband thrown in, and competing against a host of existing services, is this a case of too-little, too-late?
