In January 2005, TripAdvisor reached one million published reviews and opinions, then grew to 10 million in June 2007, 25 million in July 2009 and now features 50 million reviews and opinions — more user-generated content than any other travel site.  TripAdvisor currently publishes 25 new contributions every minute thanks to its active traveler community of more than 20 million members worldwide.

"When we first launched TripAdvisor we knew there would be an appetite among travelers for honest reviews written by real people. Eleven years later, we are tremendously proud to have reached 50 million reviews and opinions which help over 40 million travelers a month around the world plan and experience the perfect trip," said Steve Kaufer, founder and CEO of TripAdvisor.
