Comcast will increase its current 300GB data cap for residential Internet customers to 1TB per month.

"In our trials, we have experimented with different offers, listened to feedback, and learned a lot," Marcien Jenckes, executive vice president of customer services at Comcast, wrote in a blog post.

"We have learned that our customers want the peace of mind to stream, surf, game, download, or do whatever they want online," he continued. "So, we have created a new data plan that is so high that most of our customers will never have to think about how much data they use."

All data plans in trial markets will move to 1TB by June 1, regardless of current speed tiers.

More than 99 percent of Comcast users "do not come close," to 1TB, according to Jenckes, who said typical customers require only about 60GB. With a 1TB, they could stream about 700 hours of HD video, play 12,000 hours of online games, or download 60,000 high-resolution photos.

Those who want more data can sign up for an unlimited plan (an extra $50 per month) or purchase additional buckets of 50GB for $10 each.

Comcast first introduced data caps for residential customers in October 2008, following accusations that the company was cutting off bandwidth hogs without warning, kicking off the net neutrality debate that continues today. Comcast ditched the 250GB limit in 2012 and replaced it with 300GB limits for certain tiers and regions.
