Zagat Survey (pron.: //) was established by Tim and Nina Zagat in 1979 as a way to collect and correlate the ratings of restaurants by diners. For their first guide, covering New York City, the Zagats surveyed their friends. As of 2005, the Zagat Survey included 70 cities, with reviews based on the input of 250,000 individuals reporting over the years. In addition to restaurants, Zagat guides rate hotels, nightlife, shopping, zoos, music, movies, theaters, golf courses, and airlines. The guides are sold in book form, and formerly as a paid subscription on its web site.
Rating system 
The ratings are on a 30-point scale, made up of ratings for defined areas including food, decor, service, and cost. (30 is the highest rating on the scale and 1 is the lowest) In addition to numeric scores, the survey also includes a short descriptive paragraph that incorporates selected quotations (typically a few words) from several reviewers' comments about each restaurant or service, as well as typical pricing and other information.
On September 8, 2011 the company was acquired by Google for a reported $151 million. Google planned to use the acquisition to provide more content and reviews for its locally-oriented services. Google had initially planned to acquire competing site Yelp instead. On May 30, 2012, Zagat was officially integrated into Google's services, with its reviews now appearing on Google Maps and Google+ Local pages for relevant restaurants. Additionally, the Zagat.com service became free to use, but now requires a Google+ account to register.
