Fab.com: How do I know which license tier I have?

Hmm it says "You are only eligible for a Personal - Reference Only tier or Personal tier if, at the time of the Transaction you, together with any controlling entity and other entities under common control with you, have not generated more than $100,000 USD in gross revenue from your commercial activity in the digital content industry in the last 12 months. "

I’m not sure what counts as “digital content industry”
