The highly successful travel website Trip Advisor was founded in February 2000 in a small office above a pizza shop called Kosta’s in Needham, Massachusetts, USA.
(15 years later and the reviews on the site now have more than 10 billion words, that’s nearly 12,000 times the number of words in the complete works of Shakespeare.
The most reviewed city is London – with over 1.8 million reviews of the city’s hotels, restaurants and attractions.)
