This is a two-part answer. In many ways, it's not saturated yet because there are still plenty of television and film watchers who do not choose over-the-top media as their primary means of delivering content into their homes. There is a lot of market share left to seize. However, for the time being, unless more people convert to over-the-top media, the market will become flooded with more providers than consumers who are willing to pay.  You must stand out in what is becoming a very crowded field that is only going to get more congested as the years continue on.
