More people in the US access the internet via high-speed broadband connections than by dial-up narrowband, according to new figures from internet audience measurement company Nielsen/NetRatings.

Broadband usage has risen by 47% in the last year to reach 51% or 63 million, while the number of narrowband lines has fallen by 13% to 61.3m.

The 18–20 year-old age group tops the broadband penetration level at 59%, as Nielsen/NetRatings senior director of analysis Marc Ryan described this as 'not surprising' in 'the younger set of adults, kids and teens, who grew up with PC technology'.

It's also food for thought for advertisers, keen to use animation and games alongside high-grade video applications and adapted TV commercials that can only be supported by high-speed internet connections.
