Special Report: Broadband in America
According to Leichtman Research, more than 60 percent of US homes now have broadband connections. The combined total number of broadband subscribers is over 56 million at the end of first quarter 2007. In the past year alone, the top broadband providers added 10 million subscribers. But a decade of rapid growth may be coming to an end. The end of 2007 marked the third quarter in a row of declining adoption numbers, and many researchers say that the industry may have finally run out of room to grow. UBS research analyst John Hodulik is one of them. He calculates that about 76 percent of eligible homes (that is, homes that have both a PC and access to broadband service) have already signed up, so there's not much potential for further expansion.
