Right now in most markets the way broadband is delivered to the home is broadband on the cheap. Remember broadband service is delivered in most markets via NO NEW WIRES technology. ADSL2+ and DOCSIS 3.0 are the latest way for the Telcos and CATV Industry to deliver broadband service on the cheap, by not having to invest in new infrastructure to the home. Verizon and AT&T deploying new infrastructure in limited markets for delivery of broadband and other services. If we leave it to the incumbent ISP's to deploy high speed broadband to consumers, consumers will get Gigabit speed in twenty years, with 5 Gigabyte caps.
Edit: Check out this link: »inst.eecs.berkeley.edu/~eecsba1/···se1.html It connects to a webpage that describes the evolution of the telephone system as a regulated monolopy and how the regulation of AT&T and the Bell System evolved. The problem with DSL Broadband service is that it considered an unregulated overlay to the Voice Telecommunications Services. The same holds true for voice mail and custom calling services. Access to broadband service in todays economy, is so critical that all broadband service should be regulated.
If we leave it to the incumbent ISP's to deploy high speed broadband to consumers, consumers will get Gigabit speed in twenty years, with 5 Gigabyte caps.
Considering the lack of progress exhibited during the last seven years when it was left almost entirely up to the incumbents, 20 years is too optimistic for Gigabit speed.
