Virgin Media, the UK’s predominantly cable-based broadband network operator, said that its 100Mbps fibre optic service is now available to four million homes in the country.

The company said that service is now available to 100 towns in the UK, and plans to make the service available to its entire network, with a reach of 13 million people, by mid-2012. Virgin Media charges £35 a month for the service when taken with a Virgin phone line, and £45 a month as a stand-alone product.
