San Diego, Phoenix and Detroit are the top three broadband enabled cities in the United States, according to Nielsen-Net Ratings. The results are surprising. The so called technology and commercial hubs are pretty low down in the list: New York is #4, San Francisco is #8 and Boston rounds off the top ten. Baltimore led all United States cities in terms of narrowband connections, with 50 percent of the homes there connected to the Internet via narrowband. I guess it is to do with the total size of the city, and also the demographics of the city. I am pretty sure, people in San Francisco and New York who desire a broadband connection already have it. The study also does not take into account the free Wi-Fi connections, because if it did I think all the tech-and-money hubs will be way up in the ranking.
