Ubisoft and Fox Sports are among a growing number of companies halting advertising on Elon Musk's social media platform X, formerly known as Twitter. The two companies follow big names like Apple, Disney and Paramount Khabar Engadget. Elon Musk approved a post deemed anti-Semitic. "Jews have a dialectical hatred of white people," the post said.

In a comment on that post, Musk wrote: "You are telling the truth." Musk has been criticized since the incident. Some say he should be fired. Sports broadcaster and video game company Wibisoft told NBC News it is halting activity on the platform. 

Media companies including Warner Bros., Discovery, Disney, Comcast, NBCUniversal, Sony, Paramount Universal and Paris Hilton have previously announced they would stop advertising on X. In contrast, the NFL said it had decided to continue working with X. X could not be reached for comment.
