2 years that changed the pr0n industry

From James Wolcott’s “Debbie Does Barnes & Noble” (Vanity Fair: 22 August 2005):

In terms of production techniques, two years mark key inflection points in porn. The first was 1982, when X-rated producers abandoned celluloid for videotape. The other pivotal year was 1998, when Viagra was introduced. Performance anxiety, begone!
