The revelation that Comcast is putting a number to the ambiguous 'fair usage' terms widely used by broadband service provider. It has been set at 250GB per month for residential users.
I make that around 583 hours of streaming at 1Mbps. I would suggest that anyone watching more than this has issues, so this seems a fair level, at least until 'HD' services are made available, then this reduces to around 75 hours, or 2 hours a day.
It's a fair level, in my opinion and brings clarity to an obfuscated industry. It also throws down the gauntlet to ISPs around the world, who, I suspect, had hoped for a much lower bar to enable them to improve their ARPU.
