Virgin Media has turned on its first Wi-Fi services on the London Underground at King's Cross and Warren Street as it aims to provide services across the network in time for the Olympic Games.
After launching these networks on Thursday, the firm will then switch on Green Park and Oxford Circus on Friday, followed by Euston and Victoria on Saturday.
A total of 82 stations are set to go live in time for the Olympics with a further 40 online before the end of 2012.
At first services will be free for visitors and citizens alike during the Olympics but once the Games are over the firm will begin charging for access.
Gareth Powell, London Underground's director of strategy and service development, heralded the switch-on as a vital step in the development of the ancient transport network.
"Our new Wi-Fi service is a fantastic deal for Londoners, with live travel updates, entertainment and news freely available to everyone while they are on the move across the capital," he said.
"Wi-Fi at Tube stations will help us improve the journeys of the millions of people that use the Underground everyday."
Mayor of London, Boris Johnson, added that the development was another feather in the cap for the city as it looks to attract and retain world class IT talent.
"We need to ensure London is able to cement its position as Europe's leading digital city," he said.
"Our partnership with Virgin Media to make Wi-Fi available on Tube platforms will be of tremendous benefit as building world class connectivity is critical to supporting new businesses and the jobs they create, especially in the high-tech and creative sectors."
