The US Justice Department is considering breaking up Alphabet Inc.'s Google after a court ruling found it monopolized the online search market. This would be the first attempt to dismantle a company for illegal monopolization since the failed effort to break up Microsoft two decades ago. Other options include forcing Google to share more data with competitors and implementing measures to prevent it from gaining an unfair advantage in AI products. These actions aim to level the playing field and ensure fair competition in the tech industry.
