Interestingly, when we consumers start paying for content, this will provide a business model for any content and service provider. I for one, am subscribed to a independent news agency; Their subscription fee gives me NO ADs + independent research not pushed by advertisers, or hold back by advertisers. Within a year they were able to gain about 60.000 paid members, all Dutch since the content is in Dutch language. 60.000 from a population of 17m is quite a bit. This tells me when done right, people are willing to pay for good and quality content. The blockchain and the money a blockchain creates is another way to finance; However I give it another decade to become more mature.
What is also an interesting development, but still not rolled out in to many sectors is the VRM model: the consumer indicates what he/she wants, and the producer/seller can make their offers. When we deploy this for everything we as consumers want to buy, advertisement as an art/task could be completely abandoned. What a nice world would that be!?
