That said, revenue estimates for the porn industry vary widely. Some
believe the industry does not even make $6 billion a year, while others say it makes
$10 billion,
$15 billion, or even
$97 billion. Because most porn firms are privately held, it’s impossible to get a completely accurate estimate, Helmy says.
“The safe estimate is to say it’s worth billions, but I don’t know exactly how many billion, and no one does,” said Dan Miller, managing editor of AVN, another trade publication covering porn.
