However, the DOJ may be on the right track in its recently-filed antitrust suit against Google. The suit, in which the Department is joined by the Attorneys General of California, Colorado, Connecticut, New Jersey, New York, Rhode Island, Tennessee, and Virginia (so both Democrats and Republicans), alleges that Google monopolizes key digital advertising technologies that website publishers depend on to sell ads and that advertisers rely on to buy ads and reach potential customers.

I have some litigation experience in antitrust, but it’s been years since that involvement and even then I wasn’t a specialist in the area. In addition, I don’t know many facts about Google’s monopolization (or not) of digital advertising technologies.

However, I think I know this fact: Google injured at least one website publisher — Power Line. Its ad revenue dropped significantly when Google, to borrow the words of the Associate Attorney General, “captured publishers’ revenue for its own profits.”
