Ten States sued Google on Wednesday for operating an illegal digital-advertising monopoly and recruiting competitor Facebook Inc. in an alleged deal to rig ad auctions that was code-named after “Star Wars” characters.The accusation, filed in US District Court in Texas, claims that Facebook turned out as a new rival to Google, challenging the Alphabet Inc. unit’s established supremacy in online advertising. Google replied by launching an agreement in which Facebook would decrease its competitive moves, in return for guaranteed special treatment in Google-run ad auctions, the lawsuit declares.Google’s inner code name for the so-called Facebook deal referenced characters from Star Wars, according to the suit, which rephrased specifics. A person familiar with the matter stated that the code name was “Jedi Blue,” after the sci-fi franchise’s Jedi Knights.
