On Tuesday, the nation's largest internet provider announced that, starting Jan. 1, it would extend its 1.2 terabyte data cap to previously-exempt service areas - meaning once you hit that limit, you'll have to pay more to use more.
After a three-month grace period, this move will leave residential subscribers in 14 states from West Virginia to Maine, plus the District of Columbia, facing surcharges of up to $100 for exceeding that limit.
