The owner of the Daily Mail website is suing Google, saying the tech company’s dominance in online advertising has harmed its business. The suit, filed Monday in federal court in New York, says Google punishes publishers’ search results if they don’t sell enough ad space through Google. Federal and state antitrust authorities have sued Google. The Justice Department alleges that Google abuses its dominance in online search and advertising. A West Virginia newspaper company, HD Media, also sued Google and Facebook in January. Google said the Daily Mail’s claims are inaccurate and it will defend itself against them.
