In light of AT&T's recent announcement that they will cap their broadband internet offering (through U-Verse and regular DSL), as does COMCAST from what I understand, it really looks like this is the way future will be for broadband internet.
It seems to me the impact on existing business models such as Netflix' streaming service, iTunes, Amazon's new streaming service, Sling, etc... will be devastating. Caps may be high enough (for now) but people will definitely think twice before committing to multi-GB downloads. Also, I can't help but think that this may kill yet-to-be discovered business models that would have relied on unlimited broadband.
Am I being too gloomy or is the door slowly closing on many internet-related future opportunities?
Also, unlimited is an awfully big amount, and if your business model depends on unlimited in any way, the odds are that you either haven't thought it through or that it's simply not viable.
