Internet service providers are not likely to follow BT's lead and invest further in fibre-optic broadband, according to an expert.
Mark Jackson, editor-in-chief of news provider ISPreview.co.uk, has claimed that most of the company's rivals are currently using "cost-saving methods" to deploy new networks and are only likely to boost their spend if they are given government support.
He made the comments after it was revealed BT is to more than double the availability of its fibre-optic broadband network over the next few years, which means ten million homes could have access to the technology by 2012.
Discussing the plans, Mr Jackson explained that the news is "undoubtedly a positive move", as more homes and businesses will have access to super-fast download speeds.
"This is critical for helping to keep the UK's infrastructure at the forefront of future internet developments and any new media economies that should result from them, such as high definition internet TV services," he added.
