I noticed this in Bangkok. They have a nice sky train system that is cheap as shit and seemed to run well (on time, clean, not too crowded at rush times). However, all the cars have constantly looping video ads with audio. I don't know Thai so it was easy for me to tune out, but if I did and had a daily commute on those trains I think it would drive me nuts.
