Apple's stock price dipped slightly in Tuesday's late afternoon trading while Alphabet shares rose 1%, signaling investors were unfazed by the developments in Europe. Those three cases foreshadowed expanded efforts by regulators worldwide to crack down on the tech industry. The EU has since opened more investigations into Big Tech companies and drew up a new law to prevent them from cornering online markets, known as the Digital Markets Act. European Commissioner and Executive Vice President Margrethe Vestager said that the shopping case was one of the first attempts to regulate a digital company and inspired similar efforts worldwide. "The case was symbolic because it demonstrated even the most powerful tech companies could be held accountable. No one is above the law," Vestager told a press briefing in Brussels. Vestager said the commission will continue to open competition cases even as it enforces the Digital Markets Act.
