Yelp has become Google's most tenacious pest, and despite the public outcries the crowd-sourced reviews website has seen little mercy over the years. From an NYTimes article: For six years, Jeremy Stoppelman's (chief executive of Yelp) company has been locked in a campaign on three continents to get antitrust regulators to punish Google, Yelp's larger, richer and more politically connected competitor. He has testified before Congress, written op-ed columns and used Twitter to bash Google's behavior (paywalled). Google wasn't always a rival. At one point, it was a suitor. But out of that union that never happened was born a mighty grudge, perhaps even an obsession. At one point, Yelp held a hackathon to create a sort of alternate-universe Google, the better for it to explain Google's ways to regulators. And then you have Luther Lowe. Mr. Lowe, Yelp's vice president for government relations, once spent $3,000 on a stuffed elephant, because it had been knit by Europe's antitrust chief. Unlike Google, whose office is full of artwork and free food, Yelp's Washington presence is just a rented co-working space. So Mr. Lowe keeps the elephant at Yelp's San Francisco headquarters, where there is more room. "This is a shoestring operation," he said. But after years of trying and failing, that operation has finally landed a good punch. Last Tuesday, the European Union fined Google $2.7 billion -- the largest antitrust fine in its history -- for unfairly favoring its own services over those of its rivals. The fine was related to Google's shopping service, so strictly speaking it had nothing to do with the Yelp-Google dispute, which is part of a separate investigation into local search. Still, Yelp and other American technology companies pushed hard to get regulators to issue a bold condemnation of Google's behavior toward competitors, signing a letter that accused Google of "destroying jobs and stifling innovation." And by affirming that Google is the dominant company in online search -- something most people take for granted -- Tuesday's decision is likely to help Yelp's case.
