The reason? Too many of its customers are dropping cable and doing their TV-watching over the Internet instead, a trend that threatens to cost Comcast money. To recoup some of those dollars, Comcast is experimenting with caps on how much data you can use. Go over the limit and you’ll see a bigger bill.
Comcast used to cap monthly data use at 250 gigabytes, but ended it in May 2012 in order to experiment with alternatives to a simple cap. That August, it capped monthly data use for Nashville, Tennessee, customers at 300 GB; going over the limit costs $10 for every 50 GB. The company launched a similar plan in Tucson, Arizona, that October — 300 GB for a base plan, 600 GB if you signed up for a faster and more expensive connection.
