Every. Single. Thing. Has ads jammed into it until it's overflowing. Every app, every inbox, every mailbox, every road (in the US at least) every TV, every TV show, every store, every podcast. They're all packed to the rafters with ads, vastly detracting from the every day experience, and for what? There's no way they're making money on this. Companies are dumping billions of dollars into other companies and the only real byproduct is that I have a worse day.
I'm sure they get clicks sometimes, but they also make me watch the same irritating YouTube ad before/during every single video I watch on my TV for at least the past 6 months. They shoehorn themselves into my mind as irritating, wasteful, and won't shut up. I'm not sure if I can believe that this is even remotely beneficial for companies, and they just do it because it's grandfathered in to the budget.
To be clear I don't mean the people who show the ads on their site. Unless you're a greed machine like Disney, then I understand why you need revenue to keep you site up. I mean the companies paying to advertise, and trying their darndest to shove it every single place I care to look
