Is there a list of Internet companies (dot-coms) that have offices in
New York City?  The companies don't need to be headquartered in NYC,
they just need to have an office there.  The list should be comprised
of companies whose web sites are their businesses.  The following
would be examples of such companies (although these may not
necessarily have an office in NYC): ebay.com, yahoo.com, amazon.com,
buy.com, ameritrade.com, monster.com, etrade.com, expedia.com,
travelocity.com, priceline.com, ask.com, altavista.com

can't forget google.com
