Virgin Media has started selling its new 100mbps broadband service. Customers in some locations can now sign up to the superfast service for £35 a month. Virgin says the service should be available across its network by mid 2012. It added that the service has the potential to carry speeds of up to 400mbps in the future. Rival BT is also rolling out its Infinity fibre broadband network that it says will bring superfast internet speeds to most of the country. Culture minister Jeremy Hunt says the government is committed to ensuring next generation broadband is available in every community and will encourage firms to invest heavily in it. Virgin is also poised to release a new TV on demand package powered by TiVo.
