Could Google become one of the world's largest Internet providers? Rumour has it that the company has been shopping for miles and miles of "dark," or unused, fiber-optic cable. What advantage might this bring? Well, currently when a user performs a search on Google, the data is transmitted over a network owned by an ISP, and Google has to pay as much as $60 per megabit per second per month in IP transit fees. By cutting out the middlemen, Google could save millions of dollars a month.
