"than the producers want to provide"
Yes this is the analogy to TV where the market provided precisely 3 channels (plus PBS) for decades and a third of the population reliably watched each show on each channel, but that was 1970 and now in 2010s there's 500 cable channels and a wildly success narrowcast might reach as many as 1 in 40 citizens. Usually far less, of course, as little reach as 1 in 300 is possible with aggressive enough advertising budgets. Of course there is the superbowl but its only a couple hours per year and there's only one and that one is already here.
It has certain implications for future startups. It would be doom for current startups that financed assuming they'll be the one site that all 6 billion humans use. If the social media market follows the TV model, in 20 years we'll be back to multiple tribal sized BBSes, more or less, with the occasional temporary cultural fad resulting in short term scaling headaches. For about a month, about a billion of us, will try to simultaneously log into the pokemon go server, then we'll all try to forget it ever happened, which actually is a big enough problem to keep many engineers employed.
I'm not sure the financial markets know what to think of legacy TV right now, much less what will, by then, be legacy social media.
How do you finance or account for a one month pokemon go, times hundreds per year, when thats the new normal not an aberration?
