BRUSSELS, Oct 9 (Reuters) - Alphabet unit Google on Tuesday challenged a record 4.34-billion euro ($5 billion) fine imposed by European Union antitrust regulators three months ago for using its popular Android mobile operating system to thwart rivals.
"We have now filed our appeal of the EC's Android decision at the General Court of the EU," Google said in an email. It had previously said it would take the case to Europe's second highest court in Luxembourg.
