First birth year(s) that grew up on social media?

What do yall think was the first birth year that grew up on social media? When I say growing up, I mean as like actual kids not 15/16 year olds. My birth year is 2003 and I feel like we at least grew up on Facebook but I don’t know many people born in the 1990s so do you think they grew up with it too? I’m just curious y’all’s opinions!
