The use of the mobile Internet in Britain grew eight times as fast as the growth of the PC Internet, according to the latest study from research firm Nielsen Online. Of course, the actual number of Britons surfing the PC Internet is much higher. A recent report found that from April to September in 2008, the number of Britons using the mobile Internet increased by 25 percent, from 5.8 million to 7.3 million. However, the number of Britons surfing the PC Internet is 35.5 million, up only 3 percent. As expected, the report found that the mobile online audiences are younger than the PC-based users, with 25 percent of mobile Internet users aged 15-24 years old, compared to 16 percent for PC-based users. Also as expected, there are more people aged over 55 surfing the PC Internet (23 percent) than those on the mobile Internet (12 percent). This last figure —12 percent of those aged over 55 surfing the mobile Internet, however, surprised me because I had expected to be lower. Mobile audiences are interested in sites that can provide immediate information, or immediate access like BBC News, Google Search, Sky Sports, BBC Weather and G-mail. BBC News is visited by nearly one in four British mobile Internet users, or 1.7 million people. Three of the most popular sites, BBC Weather, Sky Sports and G-mail, actually have a greater reach on the mobile Internet than they do on the PC Internet. BBC Weather gets 21 percent of all mobile users with 17 percent on the PC-based Internet.
