Come Monday, AT&T will begin restricting more than 16 million broadband users based on the amount of data they use in a month. The No. 2 carrier’s entry into the broadband-cap club means that a majority of U.S. broadband users will now be subject to limits on how much they can do online or risk extra charges as ugly as video store late fees.

AT&T’s new limits — 150 GB for DSL subscribers and 250 GB for UVerse users (a mix of fiber and DSL) — come as users are increasingly turning to online video such as Hulu and Netflix on-demand streaming service instead of paying for cable.

With the change, AT&T joins Comcast and numerous small ISPs in putting a price on a fixed amount of internet usage. It’s a complete abandonment of the unlimited plans which turned the internet into a global behemoth after the slow-growth dial-up days, when customers were charged by the minute and thus accessed the internet as sparingly as possible.
