Sky's broadband service has built up a customer base of over 1 million in just under 14 months, making it the UK's fastest growing broadband provider.
The firm claims that this performance means it has reached the landmark faster than any other UK broadband provider.
Around 30 per cent of its customers have joined Sky Broadband are new Sky TV customers, while the remainder have opted for the paid-for offer, the company said.
James Murdoch, Sky's chief executive, said: "Sky entered the broadband marketplace because we saw an opportunity to challenge the established players and give customers something better.
"Our aim is to meet the hunger for better quality, better service and better value, so to be the choice of one million customers after just 14 months is a real achievement."
To coincide with news of the company's performance, Sky also revealed it had conducted a survey which revealed that 82 per cent of its customers use the internet every day.
The most popular online activities are shopping, banking and e-mailing and direct messaging friends and family, according to Sky's study.
