The European Commission has opened an investigation into whether Google is dominating the online-advertising market at the expense of its rivals.

It will examine Google’s role in collecting data, selling advertising space and acting as an online-advertising intermediary.

The commission is concerned the technology giant is making it hard for other online advertisers to compete.

Google has said it will co-operate with the inquiry.
