The U.S. Congress has mandated that the Federal Communications Commission (FCC) encourage the deployment of advanced telecommunications. Therefore, the FCC reports annually on the adoption of Internet service access nationwide. This report for 2006 notes a 61 per cent increase in high-speed access from 51.2 million subscribers to 65.0 million. High-speed access is provided by cable modems for 38.9 per cent of customers and by ADSL for 30.8 per cent. Other high-speed access modes include fiber optics, satellite, broadband over power line (BPL), and terrestrial mobile. High speed is defined as faster than 200 kbps in at least one direction. 59.5 millions lines were faster than 200 kbps in both directions, of which 53.6 per cent were cable and 39.1 per cent were ADSL.
