Mobile internet use is growing while the number of people going online via a PC is slowing, analyst firm Nielsen Online has found. Some 7.3m people accessed the net via their mobile phones, during the second and third quarters of 2008. This is an increase of 25% compared to a growth of just 3% for the PC-based net audience – now more than 35m. It also found that the mobile net audience was younger and searched for different things.
