The chief of BT Vision has played down reports that the IPTV service has performed poorly since its arrival on the market.
Dan Marks was responding to an article in Market Week which suggested that the take-up of the service - which allows on-demand TV content to be viewed through a broadband connection - has been slow.
Speaking to the Daily Telegraph, Mr Marks said that the first years of other fledgling TV services in the past indicated it was not time to panic.
He commented: "We've had extremely rapid growth compared to other platforms, look at the early days of cable or Sky".
Even with the BT customer base currently standing at 350,000, Mr Marks insisted he was still confident of meeting a target of three million subscribers by 2010, saying "we still feel we can stick by those projections".
A more realistic year to meet that target could be 2012, by which time BT plans to have connected ten million homes to its fibre-optic broadband service, improving the delivery of BT Vision.
