Government aims to cut pirate P2P 80% The UK government thinks it can reduce illegal file sharing of music and films by up to 80 per cent over the next three years. The goal was outlined by Baroness Vadera, the business minister, following the agreement the government struck with ISPs and the film and music industries to curb illegal file sharing. Industry estimates put the number of illegal file sharers in the UK at between 6 and 7 million people. The agreement requires the UK's six biggest ISPs - BSkyB, Tiscali, BT, Orange, Virgin Media and Carphone Warehouse - to send out 1,000 letters a week to subscribers identified as having engaged in illegal uploading or downloading of music. In a week when the US Federal Courts ruled Comcast mustn’t ‘shape’ file sharers broadband service, Ofcom says it will use measures, including slowing internet speeds or blocking content, to deal with repeat offenders. Rights holders will consider prosecuting "particularly serious infringers".
