Supply, demand, convenience, profit seeking. It is the way business aligns. In the not too distant past, a company would have to offer something relatively useful in order to sell a product, now they have to offer something entertaining. Even schools have taken a "learning should be fun" approach and sticking kids on tablets, when that is not actually the best way for kids to learn. A few hundred thousand years of no fun learning, and suddenly that is no longer suitable in the last few decades.
