Why does OOH ever?

Just as I was learning about how effective digital marketing is. I wondered today, while paying off most of my outpost outstanding balance for doing a OOH. Does it make sense for me to spend any more money on OOH next year? Execution not alone, strategizing the how-to's cost me $millions. I am not sure if I should invest any more in the OOH.... Attached is something that I have done this week. It makes sense for me to do something like this...……………. ever?
