Tech giant Nvidia is now worth over $3.2 trillion, with its dominance as a chipmaker making it the poster child of the artificial intelligence boom. After the stock's swift rise on Wall Street it briefly topped Microsoft as the most valuable company in the S&P 500 this week. And it's an unlikely piece of technology — graphics chips initially invented to create more realistic video games — that has propelled the company to AI fame.

An oversight board is criticizing Facebook owner Meta's policies on manipulated media as "incoherent" and insufficient to address online disinformation in a major election year. The quasi-independent board said on Monday that an altered video of Joe Biden on Facebook exposed gaps in the policy. The Biden video didn't violate the company's policy because it didn't misrepresent anything he said, but the Meta Oversight Board said such visual content should be labeled in the future. It urged the company to expand its policy to focus on media regardless of how it was created and to label images, videos and audio clips as manipulated instead of removing the posts altogether. Meta said it welcomes the board's ruling on the Biden video and is reviewing the recommendations.

Starting this month, some new personal computers that run Microsoft's Windows 11 operating system will have a special "Copilot key" that launches the software giant's AI chatbot. Getting third-party computer manufacturers like Dell to add an AI button to laptops is the latest move by Microsoft to capitalize on its close partnership with ChatGPT-maker OpenAI and make itself a gateway for applications of generative AI technology.

Google is confronting a threat to its dominant search engine as federal regulators launch an attempt to dismantle its internet empire in the biggest U.S. antitrust trial in a quarter century. Over the next 10 weeks, federal lawyers and state attorneys general will try to prove Google rigged the market in its favor by locking its search engine in as the default choice in a plethora of places and devices. On Tuesday, prosecutors opened their case by saying it's about the future of the internet and whether Google's search engine will ever face meaningful competition. Google is arguing that competition from Microsoft's Bing, Amazon and Yelp keep the marketplace fair.

The U.S. government is taking aim at what has been an indomitable empire: Google's ubiquitous search engine. An antitrust trial will swing into full force Tuesday in a Washington D.C. federal courtroom. The case marks the biggest U.S. antitrust trial since regulators went after Microsoft a quarter century ago to challenge Microsoft's dominance in personal computer software. The 10-week trial comes years after the Justice Department alleged Google abused the power of its search engine in ways that stifle competition. The government says Google's practices increasingly force consumers to settle for inferior search results.
