HBO is losing the popular "Sex in the City," but to lessen the blow the cable network has commissioned a six-part documentary called "Pornucopia: Going Down in the Valley," about the adult video biz in the San Fernando Valley. Tomorrow's Variety says the show will ''investigate how porno gets produced, distributed, marketed and consumed." The producer and director is Dan Chaykin, who has produced newsmagazine pieces for CBS and ABC. Executive producer is Steve Ziplow, described by Variety as a record producer and author of A Filmmaker's Guide to Pornography.

So much for original programming. A quick Google search finds that one porn actor already has the credit on her resume.
