From an article at Digital Media Europe:

There are over 400 cities worldwide currently planning to deploy municipal broadband networks, and that number will double in 2006, making community broadband initiatives a very real and significant trend, according to a report from market research firm Visiongain.

Despite legal opposition and intense lobbying from incumbent telcos and cable companies, municipal broadband is well on its way. As of the first quarter of 2006, there are over 100 city and regional wireless broadband networks operational worldwide, more than 40 of which are in the US.
