LOS ANGELES — Was CNBC’s porn special last night too taboo for corporate America?

Mediaite, which follows the media scene, reports that investment services provider Charles Schwab canceled its advertising on CNBC during the time when the business news network planned to air “Porn: Business of Pleasure.”

“According to multiple sources, Charles Schwab, a regular sponsor of the ‘Fast Money’ program, as well as others, pulled its sponsorship from the program after a preview segment made it seem like Schwab was associated with the sex doc,” a story said on the site.

Indeed, most of the advertising during Wednesday night’s program consisted of infomercials and of the “as seen on TV” variety.

“When asked directly about Schwab’s decision to drop its sponsorships, a CNBC spokesperson told Mediaite, ‘No comment,’ but added, ‘The Business of Porn’ is a fantastic documentary which will give CNBC viewers insight into a $15 billion industry,’” Mediaite said in a post.

But there always is a faction that wants to give the adult entertainment industry a hard time. On Monday, news site NewsBusters.org, owned by the Christian-based Media Research Center, included a story titled, “CNBC Special Promotes Porn.”

The story’s lead read, “’Porn: Business of Pleasure’ is nothing more than an attempt to normalize, and even promote, the porn industry.”
