Someone can run campaign to promote it. Then we'll see the price going up due to its increased adoption!
Not in this way at least, we can't expect someone to pay from their pocket to advertise bitcoin. I highly believe that services that run in bitcoin, offer/accept bitcoin payments or any other field related with bitcoin then these are who advertise for their services.
How about aditya6997 starts to promote bitcoin, since it is his idea to run a campaign to promote Bitcoin. But I bet he wouldn't because he does not have any company or service that will benefit from that advertisement.
Usually people do not make big advertisement without any profit or any advantages of their business so I doubt someone with advertise in this way, if you have a third party service and it related with bitcoin then it make sense.
