Porn in the Valley -- Part IV

The porn industy has gone mainstream.

Nautica Thorn was strolling the aisles at Blockbuster one night, just browsing for a video, when she did a double take.

There, on the shelf amid the action films and romantic comedies, sat a sex-laden adventure on the high seas starring porn stars Jesse Jane and Janine.

"I was just getting a movie to watch and I saw `Pirates.' I thought, `Wow, that's cool,"' Thorn said. "When I was a kid, I remember staying up late at night with the cable box, watching the little squiggly lines, hoping you could see something. You were like, `Ooh, I think I can see something."'

Thorn's shock is surprising, seeing as how she's a porn actress herself. And she knows firsthand how the adult industry flirts with mainstream appeal and exposure.

The 23-year-old star of "Teeny Tarts 4" and president of Hollywood-based Nautica Thorn Productions made a name for herself getting naked on camera. That name pushed her into mainstream consciousness recently as she appeared on the Fox reality show "My Bare Lady," which featured four porn performers trying to make it in London theater. Produced for a major network and now available for sale on iTunes, the series completely relies on the idea that people like to watch sex on TV.
