Google has won a court challenge against a 1.49 billion euro European Union antitrust fine imposed five years ago that targeted its online advertising business.

Google won a legal challenge Wednesday against a €1.49 billion ($1.66 billion) antitrust fine from the European Union, while chipmaker Qualcomm failed to repeal a penalty.

Antitrust officials had imposed the fine over how the search giant might have restricted the way that some websites displayed ads sold by its rivals.
