With the adoption rate of high speed connections growing and users increasingly getting their movies and music from the web rather than traditional outlets, ISP Time Warner Cable announced that they will begin experimenting with billing their customers based on Internet usage per month, rather than a traditional flat rate. The company plans to launch a trial program starting in Beaumont, TX, in which new customers will be offered tiered levels of service based on how much data they send and receive per month. Exact prices have not been released, nor has an exact date been determined, but it's probably a safe bet that other ISPs will be watching this one closely.
