It was announced on 8 February 2007 that BSkyB intended to withdraw Sky Three, Sky News and Sky Sports News from the platform in the summer of 2007. BSkyB had said that it intended to replace them with 4 of its subscription channels. It also said that it would use an alternative (MPEG4) codec, which would enable a greater number of channels to be broadcast, but would require the purchase of new equipment for those who wished to receive the new service. On 6 October 2007 Ofcom said that the plans for a new subscription service raised competition concerns and may have to be scrapped.
