TripAdvisor Grows and Grows and Grows

Now 45MM Reviews and Opinions, With 23 New Contributions Every Minute Now Operating in 29 Countries in 20 Languages

LONDON, April 12, 2011 - Eleven years ago, in February 2000, Co-Founder and CEO Stephen Kaufer
started TripAdvisor(R) with the ambition of creating a site to help
travellers plan and have the perfect trip, with reviews written by and for
real travellers. TripAdvisor, today the world's largest travel website*, now
has 45 million reviews and opinions, with 23 new contributions posted every
minute. Five million reviews and opinions have been added since October 2010.

To coincide with the growth in content, TripAdvisor has expanded its
global reach. Since the beginning of 2010, sites have launched in Argentina,
Greece, Indonesia, Russia, Korea, Singapore, Thailand, Australia, Norway,
Poland, Taiwan and-most recently-Malaysia. TripAdvisor now operates in 29
countries and is available in 20 languages.

"TripAdvisor continues to experience remarkable growth because travellers
the world over find exactly what they're looking for on the site: a wealth of
travel-planning tools and the reviews and opinions of millions of other
travellers, including their own friends," said Kaufer. "Since our launch over
a decade ago, we have expanded not only our travel-planning features to
include Flights, Vacation Rentals, Attractions, and so on, but we have also
expanded our global reach. We're now in nearly 30 countries."
