StumbleUpon Celebrates Five Million Registered Users and Five Billion Stumbles

With more than five billion Stumbles to date, discovery is gaining ground on
traditional search

SAN FRANCISCO, April 24 /PRNewswire/ -- StumbleUpon
(http://www.stumbleupon.com), one of the most popular ways to discover new Web
sites and videos on the Internet, announced that it has reached a major
milestone of five million registered users and almost five billion 'stumbles'
since its debut in the fall of 2001 -- with over one billion 'stumbles'
to-date in 2008 alone. A 'stumble' equates to a Web site delivered to a user
when they press the Stumble button on the StumbleUpon toolbar.
"Reaching these incredible milestones is evidence that people need and
want a personalized way to discover great content on the Web," said Michael
Buhr, general manager, StumbleUpon. "People are looking beyond traditional
search for better ways to sift through the vast amounts of content online and
discover what is interesting, useful and relevant to them."
Online content is growing exponentially year-over-year and, according to a
recent IDC study, individuals are now spending more time on the Internet than
they do watching television. This combination has created huge demand for
solutions that help people quickly and easily discover personally relevant Web
sites, online videos, photos, blogs and other online content. With
StumbleUpon, people are tapping the wisdom of crowds to get personal
recommendations of great Web sites and Web content that matches their needs
and interests and, more importantly, content they would not have found via a
traditional search engine.
As traditional search continues to move at a steady pace, StumbleUpon's
growth is skyrocketing. While a recent comScore report found a 48% growth in
U.S. online searches from March 2007 to March 2008, StumbleUpon saw an
impressive 134% increase during the same period. Additionally, if stumbles
would have been counted on comScore's most recent U.S. Search Engine Rankings
study, StumbleUpon would have placed ahead of Facebook and Amazon. These
findings, coupled with StumbleUpon's rapid momentum, further prove the need
for tools that help users cut through the clutter of the Web in order to
discover what's personally interesting and relevant to them.
