Mediums are always evolving. However we are all witnessing more free information and support being given to people. The quality of free information has increased rapidly and many of the products that a market would have paid for last year are now available at no cost.
It is also clear that as competition increases there is a deeper need for the "faces" behind info products to also build more credibility. Majority of them are doing this by creating and growing communities on Facebook and building YouTube channels with massive subscriber lists. All of this is created off the back of high quality content.
