Just took a look at my comcast account. I ditched cable tv and now watch everything thru the internet. I was over 370GB in February, 260 in March, and 202 in April. Moving the max to 300GB will help me avoid more nastygrams.
I would say the LEAD horse in this effort is Carlos Slim Helu, he owns so many Telecomunications in Latin America, and just recently Tel Mex told it’s customers in Mexico that they would start paying for content downloaded...
My wife streams Russian TVoIP (in HD) on the living room TV, my kids watch children's programming on Netflix and I pretty much just watch Netflix as well. In a week, I doubt if we watch an hour's worth of regular cable. I've breached Comcast's 250GB ceiling in the entire 13 months I've had Comcast. To be fair, they never sent me any nastygrams or otherwise restricted my service. Last I checked, they removed the link that showed me my usage but prior to that, we always exceeded 300GB.
I knew it would only be a matter of time before the cable companies went this route, especially with customers like me who scaled back their cable plans while eating up GB by streaming video content.
