High-speed internet access is now in 95.5 million US homes and is changing the way people use their computers.

A new survey by Nielsen/NetRatings shows the average person now spends 30.5 hours per month using their home PC; two years ago the monthly figure was 25.5 hours.

Broadband led nine million visitors to MSN Video in February, an increase of 44% over the same time last year. IFILM's audience increased 102% over the past year, and the traffic at Yahoo's video search site increased 148%.

John Gibs, Nielsen/NetRatings' senior media director says it is unlikely so many people would be attracted to these sites without broadband. He adds: "The fatter the pipe [the higher the speed], the more likely individuals are to download content."

The study also reveals that most of the video content available online is advertiser supported, with ads appearing either before or within the broadcast and as part of the site that hosts the video.

Avers Gibs: "Video is something you need to do in order to stay in the online news and information business."
