Porn stars are no longer underground figures but rather mainstream media personalities. Actress Mary Carey attended the United to Victory dinner sponsored by the National Republican Congressional Committee on March 16 in Washington. She ran for governor in California, has become a supporter of the Republican Party.

The industry's VIPs mingle at political galas and Super Bowl parties. Their product is available on cell phones, podcasts, and particularly the Internet - there it's an attraction like no other, patronized by tens of millions of Americans.

It's pornography. And if you're a consumer, John Harmer thinks you're damaging your brain.

Harmer is part of a cadre of anti-porn activists seeking new tactics to fight an unprecedented deluge of porn which they see as wrecking countless marriages and warping human sexuality. They are urging federal prosecutors to pursue more obscenity cases and raising funds for high-tech brain research that they hope will fuel lawsuits against porn magnates.
