Time Warner Cable has shelved its plans to shift its residential broadband customers to “consumption-based billing”, at least for the moment, as a way of controlling excessive bandwidth use by a small number of really-heavy users and maintaining quality of service for other users who share the network. Short of investing in a higher-capacity access network, it isn't clear how some way of matching consumption to cost is avoidable, long term.
But that points out one advantage Verizon Communications has: it has ample access bandwidth to provide uncapped usage, which could become a marketing weapon wherever it competes with other providers who do impose caps or other sorts of restrictions.
