Yelp has thousands of reviews on Los Angeles-based businesses that users are able to search or browse, as of 2015.
Yelp was founded in 2004 to help people find great local businesses. By the end of the third quarter of 2015, users had written more than 90 million reviews.
Yelp makes money by selling ad space to local businesses, and those ads are clearly labeled on the website. However, to keep an honest rating system, paying advertisers are not able to have reviews changed or re-ordered.
