open beta incorporated a media player, an electronic programme guide (EPG) and specially designed download client and allowed the download of BBC Television content by computers assigned to a United Kingdom-based IP address, for use up to thirty days after broadcast. However it was available only to users of Windows XP. This was a controversial decision by the BBC and led to a petition against the decision being posted on 10 Downing Street's e-petition website. The petition reached 16,082 signatures on 20 August 2007.
