Survey A market research company has claimed that end users downloading MP3 music files is causing corporate business systems to become clogged. The report, from Computer Economics, says that large corporations will need to clamp down on MP3 downloading, otherwise they will have to spend serious amounts of money upgrading their systems. According to the survey, big business spends six per cent of their IT budgets on network infrastructure, a figure which has grown from one per cent in the early years of this decade. "MP3 and any other method to deliver sound and music over the Internet is a cool idea," said market analyst Michael Ebschloe. "But the more cool an idea is, the more it can have a negative impact on a corporate network." ®
