"This service isn't about tweaking coverage, playing with sound and structures or gimmicks. This is a fundamental development and might in time change sports broadcasting.
"This is the very first truly interactive sport service to offer real choice for tennis fans and adds real value to existing quality coverage."
A Sky spokesman said: "We have carried over 1500 hours of live interactive sport over the last 18 months. That includes US Open tennis, golf's Ryder Cup, football, cricket and rugby."
The BBC refused to reveal today how much the corporation were paying Sky for the service but critics argued the license fee funded broadcaster is investing too much in a service available to just 20 per cent of the population.
Subscribers to ITV Digital (formerly ONdigital) and cable digital services like NTL will be able to watch the BBC's interactive service, but those platforms do not allow viewers to watch simultaneous games.
Meanwhile, Greg Rusedski was back on the practice court today as he attempts to sort out a slump in form. Britain's No 2 lost 6-3, 6-4 to Spaniard Alex Corretja in the first round of the Masters Series event in Hamburg.
He has now failed to progress beyond the second round of any of the six tournaments he has played since beating Andre Agassi to win the Sybase Open in San Jose in March.
