Top Business Stories from The New York Times

On November 21, several significant stories emerged on the New York Times business pages. One of these stories involved Microsoft and the upheaval at OpenAI, a small but influential artificial intelligence start-up. This led to the development of the ChatGPT chatbot and caused Microsoft’s shares to reach a new high.

In another story, X, the social media service formerly known as Twitter, sued Media Matters in federal court after the organization published research showing that ads on X appeared next to antisemitic content. Additionally, Epic Games’ chief executive, Tim Sweeney, testified in a San Francisco federal courthouse as part of the company’s legal battle against Google.

The future of OpenAI was also at stake after more than 700 of its 770 employees signed a letter saying they may leave for Microsoft if the ousted chief executive, Sam Altman, is not reinstated. The development of ChatGPT had caused upheaval at OpenAI and affected Microsoft’s share price. It was reported that this event had been closely monitored by investors in both companies.
