For years, governments around the world have waged a bitter fight with Google and Meta over whether the Big Tech giants should pay for the news stories and videos that show up in search results and on social media. Now that fight has come to their home turf — the United States.

California politicians are advancing a bill that would force Google and Meta — which owns Facebook and Instagram — to pay news publishers each time they display pieces of their articles or show links to them in search results or on social media. The companies are lobbying furiously to block it, saying the law would enact a “link tax” and upend the free flow of information online.
