The average Netflix subscriber now watches 93 minutes of online video a day just from Netflix, and that adds up to 45GB of usage on average a month.

The Diffusion Group released that estimate in a new 35-page report (priced at $2,495) based on streaming data released by Netflix, and it shows a 350 percent increase in viewing over the last ten quarters, adding up to more than seven billion streaming hours in the last quarter alone.

Consumers with usage-limited broadband accounts will find online video viewing increasingly eating away at viewing allowances, but when 4K HD video arrives in the not too distant future, usage caps of 300-500GB a month will seem paltry. That new video format consumes up to 7GB per hour, and if current trends stay true, the average Netflix viewer streaming at the highest video quality could find their monthly Netflix traffic consumption rising to more than 300GB a month.
