We use Jupiter Research estimates for the total number of subscribers
in the United States: 83.7 million subscribers, and we also use Jupiter
Research estimates (from its broadband
analysis unit) elsewhere as noted above. This number does not include:
subscribers at work, at universities, or in government. It only includes
residential consumer accounts.
All subscriber counts are as of June 31, 2005. Note that, due to rounding,
the market share percentages in this chart will not always add up to exactly
100.0 percent even though they do for this quarter.
We do not have numbers for ATX, RCN, MSN, and several others. GCI fell
off the list because it now has fewer than 100,000 customers.
Note that Insight Broadband plans
to go private, acquired by The Carlyle Group and insiders. Adelphia
has
been acquired by Time Warner and Comcast.
DIRECWAY broadband has had zero marketing dollars for some time and our
subscriber numbers for it are an estimate based on out of date data.
We show sources for all numbers.
United Online no longer claims to be an ISP, focusing on the delivery
of services such as Classmates.com.
RCN has been restructured and declared subscriber numbers for the first
time in a while.
