A €1.06billion (£948million) fine handed down to United States chipmaker Intel in 2009 is the highest to date. The commission says Google unfairly favors its own shopping search results; Google denies any wrongdoing.
Google has 90 days to end the conduct or face penalty payments of up to 5% of average daily global revenue, the European Union said. That's a good thing.
When a person searches for something, Google will then show products at the top of your search results from various vendors and will even provide review scores if they're available.

The EU's allegations strike at the heart of a type of online advertising known as Product Listing Ads, or PLAs, that is growing at nearly three times the rate of traditional text-based search ads, according to digital marketing firm Merkle Inc. "That's why Google shows shopping ads, connecting our users with thousands of advertisers, large and small, in ways that are useful for both", Kent Walker, senior vice president at Google, said in a statement.
"We respectfully disagree with the conclusions announced today", a Google spokesperson said. The Commission did not specify what changes Google had to make.
The European Commission was prompted to take action after numerous complaints were made by rival firms such as Yelp, TripAdvisor, UK comparison site Foundem, and News Corp.

"When a company wields such power that it is effectively the gateway to the internet, it is the duty of regulators and lawmakers to verify that power is being exercised fairly". A company should not be allowed to abuse a dominant position in one area to become dominant in another area.
While the penalty is a record, it will do little to faze a company whose parent has more than $90 billion in cash.
