In the UK 20,000 homes and businesses are being connected each week to broadband services, the DTI said.
E-commerce minister Stephen Timms said, "At this pace, the UK is well on its way to being the most extensive and competitive marketplace for broadband in the world."
However, DTI-funded research carried out by Brunel University on the Korean broadband market found the Asian nation had the highest penetration of broadband in the world.
As of June 2002, more than 60% of Korean households had broadband, and the Korean government has set a target of providing 20mbps to the home by 2005. Korea reached the milestone of one million users in April 2000.
Reasons for Korea's success highlighted by the study include a clear government policy to make the country a knowledge-based economy, promising "one PC for everyone".
