You can't visit a major city anywhere in the world (North Korea is only exception I can think of) without seeing them - billboard advertising. All those billboards together total a $35 billion per year industry.Another interesting factor to consider, while online advertising has taken a bite out of virtually every other traditional advertising method, the billboard advertising industry is growing, and at a healthy rate with another $10 billion expected to be added within the next few years.Having your company's logo or message for all to see in a high traffic area, weather that's foot or vehicle traffic just isn't going to ever become 'outdated'.There's no ad-blocker plugin or fast-forward button for the real world, so when it comes to real world advertising - billboards are the king.But if you want your message on one, you better prepare yourself for massive headaches.These days you often won't be able to find who owns the billboard if you want to put your ad on, instead you'll find ad agencies that have deals with the owners to act as middlemen. They make the owner's life easier by bringing in the clients and making all the necessary arrangements.However, if you're the client you're now forced to pay both the ad agency, and the billboard owner. Bidooh says they have the solution - AI powered fully automated decentralized system that connects advertisers, publishers and consumers to the Bidooh platform. What once took a week of phone calls to multiple people is done in a few minutes and a couple clicks. They explain:Like any advertising, you'll need to write up your ad and design it - but once you have that the hard work is done. Just decide where you want it to appear, how much you want to spend (how long you'll want it to run) and in the push of a button your job is done.The billboards themselves are digital, which is why it's this simple - nobody has to climb up onto these and swap out one ad for another. I'm not going to go into a lot of detail on how a screen becomes part of the Bidooh ad network, but I will say - it looks as simple as plugging in a box they provide and connecting it to the internet.On that note however, Bidooh has a head start - they have these screens in cities already. They already do this stuff - what's new is adding blockchain and all the new features that are possible because of it.The advantages don't end there - advanced research data enables smart targeting. If you're promoting an app, target young people in a city full of tech lovers like San Francisco or Seattle. But if your product is for something like... let's say water ski's - maybe a mall closer to the Great Lakes is best.All of this will be powered by the DOOH token!Which presents a new use case as well, tokens as time - because 1 DOOH token equals 10 seconds of your ad showing on-screen, which explains why 2000 of them costs $1 in their ICO.Their ICO is live now, and ending soon - visit https://bidooh.io/
