Maybe? Every gas pump I've gone to in the past half decade has had a TV playing ads at me. So at least part of the oil company ecosystem has an ad component.
I recently moved back to a city where I rarely have to drive, which is nice, but I was driving a lot last year, and "do the pumps have those godawful TV ads or not" became my #1 criterion when deciding where to buy gas. What an unbearable racket!
Do you happen to know anybody who denies climate change? Because their talking points came from an oil company.
If lobbying governments to ignore the world slowly boiling to death is ads, then yes.
