SourcePhiladelphia-based Comcast, one of the country's largest TV and internet providers, says it listened to customers' concerns and has raised caps from 300 gigabytes a month to 1 terabyte. It says that allows for streaming 700 hours of high-definition video — around the clock for almost the entire month — or playing 12,000 hours of online games. Large households with several devices might reach the limit quickly, but Comcast says less than 1 percent of customers exceed 1 terabyte.
I asked the other day about the data cap and what it was for my new Comcast plan and yep they said 1024bg :)
