I'm amazed how much of the internet economy has turned out to be advertising. People complain about ads when they watch TV, but they'll go out of their way to spend hours watching ads on social media. And lots of kids dream about being an influencer, basically an advertiser, for their work.
One reason why I have no interest in going to facebook anymore is that the vast majority of people's social media activity on there nowadays is advertising... something. People showing their latest purchases, vacations, experiences, etc, all basically showing something they spent money on.
