I think there is still a very large and unexplored market of opt-in based advertising, this is a good example. Other examples might be at gas stations, get reduced fare if you listen to targeted ad etc. Or ads when inside an uber. I dont mind targeted advertising actually (if its actually interesting to me), sometimes I wish I could see more of it but I have adblock running everywhere Another example I see is sponsored pizza at tech meetups and sponsors etc
