I use ad blockers and open source privacy focused software whenever I can but occasionally I have to use computers that don't belong to me or an older phone where my usual applications aren't installed and seeing all the advertisements just feels dirty and dystopian.
I think the worst ads are the text to speech ones that say "Download this app today". The unblinking energenic people saying you can make a living at home are probably a close second.
Yeah, that’s why I have a bunch of VHS recordings from the 90’s. They’re like little time capsules and the ad’s of the time are telling of the events at the time.
