The Disney-owned Maker Studios and YouTube have pulled away from PewDiePie, one of the video platform’s most popular stars, after a report that he had posted several videos featuring anti-Semitic imagery.

Maker Studios said on Monday that it had severed ties with the star, Felix Kjellberg, a Swede better known by his YouTube alias PewDiePie, while YouTube said on Tuesday that it had canceled the release of a coming series and dropped him from a premier advertising program.

The announcements came after The Wall Street Journal reported that Mr. Kjellberg had posted nine anti-Semitic videos since August.

“Although Felix has created a following by being provocative and irreverent, he clearly went too far in this case, and the resulting videos are inappropriate,’’ a Maker Studios spokeswoman said in a statement on Monday. “Maker Studios has made the decision to end our affiliation with him going forward.”
