destinyland writes "Time-Warner is now mulling a plan to charge a per-gigabyte fee for internet service. A leaked memo reveals they're now watching how many gigabytes customers use in a 'consumption-based' pricing experiment in Texas, which we discussed early last month. The announced plan was that they were considering a tier-based approach, as opposed to per-gigabyte fees. 'As few as 5 percent of our customers use 50 percent of the network,' Time-Warner complains, with plans to cap usage at 5-gigabytes, and more expensive pricing plans granting 10-, 20-, and 40-gigabyte quotas. Steven Levy at the Washington post suggests Time-Warner's real aim is to hobble iTunes, raising the cost of a movie download by $10 (or $30 for a high-definition movie). Eyeing Time-Warner's experiment, Comcast cable also says they're evaluating a pay-per-gigabyte model."
