I guess one side effect of being glued to your phone all the time is that you don't notice adverts. But the tube had adverts in the 90s, and before - http://howlsandwhispers.co.uk/articles/bob-mazzer-london-und...

I did notice adverts on a flight from delhi last month on the front of a film, but it's very rare I'll watch anything on a plane's entertainment system, partly because of things like adverts.
