You thought Google would escape my ire today, didn’t you? A coalition of attorneys general representing 50 US states and territories today announced a long-awaited joint probe into antitrust complaints against one of the biggest tech companies in the world, Google. The office of Texas Attorney General Ken Paxton is spearheading the bipartisan investigation, which is beginning with the search and digital advertising markets. Google “dominates all aspects of advertising on the Internet and searching on the Internet,” Paxton told reporters during a press conference. Is anybody surprised by this? Google’s dominance in search is bad enough as it is, but the company’s real monopolistic power comes not from search, but from its more nebulous online advertising business. It’s not nearly as sexy as App Store manipulation or bundling Internet Explorer with Windows, but it’s just as potentially detrimental to the overall market as they are.
