ISP (and cable giant) Comcast said Wednesday that it’s introducing a super fast Internet service in some of its larger markets and will offer faster connections to all of its subscribers within the next two years. The company will initially roll out its wideband Docsis 3.0 in Boston, Philadelphia and Southern New Hampshire, among other areas, and introduce wideband in more than 10 major markets in the next several months. “Extreme 50” subscribers will be able to download a high-def movie (6 GB) in about 16 minutes; a standard-def movie (2 GB) in about 5 minutes and a standard-def TV show (300 MB) in seconds.
