This exposure wasn’t mainstream until the early-mid 10s when every high schooler got a phone and social media. Before then, it was computer and game system based and that changes. I don’t know real screen time data, but the use of phones probably added an extra 4-10 hours of screentime per day. And the type of activity is very different with notifications and pickups being top of mind.
