Brussels, Belgium—The European Union (EU) imposed a $5 billion fine to Google for violating antitrust regulations. Google is also banned from using its Android operating system because of its inherent blocking of rivals.

EU Commissioner for Competition, Margrethe Vestager, said, “Google has used Android as a vehicle to cement the dominance of its search engine.”

She went on to say that Google has three months to cease its anti-competitive practices or seek to delay the order. The EU arch-regulator warned that if Alphabet doesn’t comply, it could receive additional fines worth of up to 5 percent of average daily global revenue.

This is the second fine Google has been ordered to pay in two years. In 2017, EU regulators penalised the U.S. tech giant with a $2.7 billion fine because its online shopping search service (Google Shopping) was found to have an unfair advantage over the competition.
