Google announced on Thursday that it acquired the restaurant rating company ZAGAT. “ZAGAT will be a cornerstone of our local offering — delighting people with their impressive array of reviews, ratings and insights, while enabling people everywhere to find extraordinary (and ordinary) experiences around the corner and around the world,” Marissa Mayer, vice president of local, maps and location services at Google said in a blog post. “I’m incredibly excited to collaborate with ZAGAT to bring the power of Google search and Google Maps to their products and users, and to bring their innovation, trust and wealth of experience to our users.” ZAGAT was started more than 32 years ago by a couple, Tim and Nina Zagat, and the company’s ratings are now embedded in pocket guides and plastered on restaurant windows in more than 100 cities around the world and across 13 different categories. Tim Zagat confirmed on ZAGAT’s website that the couple will remain with the business as co-chairs. “Google is the first place everyone goes when looking for information; it’s the perfect home for our content,” Mr. Zagat said. The terms of the deal were not disclosed.
