IBM has stopped advertising on social media platform X after a report said its ads were appearing alongside material praising Adolf Hitler and Nazis — a fresh setback as the site formerly known as Twitter tries to win back big brands and their ad dollars. The U.S. tech company made the decision after a report Thursday by the liberal advocacy group Media Matters said ads from IBM, Apple, Oracle, NBCUniversal's Bravo network and Comcast were placed next to antisemitic material on X. “IBM has zero tolerance for hate speech and discrimination and we have immediately suspended all advertising on X while we investigate this entirely unacceptable situation," the company said in a terse statement.
