YouTube video-sharing service is the most popular website among smartphone users, accounting for 17 per cent of mobile data traffic, according to a report released Tuesday by network firm Allot Communications.
"As video streaming continues to reign supreme within mobile networks, YouTube continues as the single most significant website for video steaming and sharing, now accounting for 45 per cent of overall mobile video streaming traffic and 17 per cent of total traffic on mobile networks," said Allot Communications.
Last month YouTube said that it was serving up more than 200 million videos daily to smartphones and other Internet-linked mobile devices .
Allot Communication's Global Mobile Broadband Traffic Report for the second half of 2010 found that video streaming extended its lead over other services, accounting for 37 per cent of total traffic.
File sharing represented 30 per cent of traffic, which Allot said indicates many subscribers see mobile Internet as a direct substitute for fixed connectivity.
