Chief executive officer, DoubleClick Inc. 1997 COMPENSATION
$175,000 AGE 37 E-MAIL koconnor@doubleclick.net BIO You're
surfing the Web, checking out what's on A&E tonight, when an ad
pops up for the movie theater around the block. Is Loews paying
to advertise to a vast international audience for one little
movie house in Maryland? Nope. The website just knows who its
user is--a film buff on a Mac in Baltimore. That's the idea behind
DoubleClick, the Net's most successful ad firm. O'Connor launched
DoubleClick in 1996 with the goal of delivering a well-targeted
audience to his advertising clients. Using controversial software
called cookies, DoubleClick sites can snoop on users' browsing
habits, sometimes picking up such critical information as zip
codes. O'Connor is experienced at steering promising start-ups--at
21 he founded a software company that eventually posted yearly
revenues of $35 million. 1998 POWER PLAY DoubleClick went public
in February and in one month its shares more than doubled in
price. In July the company rolled out its localized ad service,
allowing businesses to target particular communities. PLACE YOUR BETS Most analysts say it's still too soon to tell, but some call
DoubleClick a moderate buy.
