These days, if you see what someone is doing on their laptop or phone, most of the time, they are using social media. They might be posting, commenting, or just scrolling. Social media has become a major source of entertainment for everyone, no matter their age. People are often watching videos of various things.

I think it's mainly gaming. Gaming has grown a lot, especially mobile gaming, which is now very popular. Mobile devices have improved a lot, so they can handle games with good graphics. This has caused a lot of games to be available on handheld devices. Laptops have also become almost as powerful as desktops.
