Advertising clearly does work on the whole or who would companies spend so much gold on it? Advertising shits in your head. It subtly influences consumers and advertisers have become quite sophisticated about it. There is a glut of advertising space available now so we see awful and ineffective ads but be assured a lot of the bigger players know what they are doing. This is why I block all ads. Well for that reason plus they are annoying as hell.

To be fair the aim of ads generally isn’t to make you go ‘oh now I’ll go and buy that’, it’s more about unconsciously planting the idea that $product exists so when you actually do want to buy something you buy that brand. It’s why ‘show me as many as you like, ads don’t work on me’ is complete rubbish and the only real solution is blocking them entirely on a personal level and on a social level laws that restrict where and when they may be shown.

A particularly egregious example of psychologically manipulative advertising would be ‘Joe Camel’ who was nominally just a fun mascot but in reality existed to advertise cigarettes to children so they’d buy Camels when they were old enough. Given the prevalence of really awful advertising in the present day Big Tech really does deserve the increasing comparisons with Big Tobacco I think.

To be fair, even though ads didn't make you want to buy anything, the tax write-off was the same.
