Before teenagers were looking up to YouTubers, they were looking up to TV celebs, musicians, sports players, and so on. You had entire publishing empires built around following such celebs around and reporting on their private lives.
I don't think this is hugely different. The tech has evolved and the formulas have been perfected, but it's still catering to the same obsessions and urges that we had for a good while.
