In response to a suggestion by Tom Millitzer of New
Commerce Communications, we switched to using subscriber values
without AOL.
ISP-Planet 's subscriber
values are derived from publicly announced figures. Calculation of subscriber
values is derived from the financial and subscriber information disclosures
of publicly traded companies. Subscriber numbers are derived from corporate filings and
ISP-Planet's Subscriber Rankings .
Note that because the composition of categories changes over
time, categories are roughly comparable over time, but changes can be ascribed
to the addition of companies to the list or their removal from it.
