difference between real celebrities and social media influencer fame.
Both have fans, but social media people are known almost exclusively to their fans only, and anyone who is not a fan will have no clue they exist. for the most part. a few have eclisped that level to regular fame.
Real celebrities have fames, but they can often also recognized by people who aren't fans of their work at all. If you never bought a taylor swift album and never listen to her music, you still might know her from the superbowl or from the Kanye/kardashian beef.
