I am convinced we will eventually get to a micro-payment model where we will have several options for how we pay for content:
1) High monthly-fee full service buffet from a cable-like provider with access to hundreds of channels.
2) Moderate monthly payment for whatever content one provider offers (Amazon Prime, Netflix, Hulu, etc.)
3) Lower Monthly fee to access everything a specific channel offers (HBO Now, BBC-one player).
4) Individual show or series access for fee (Amazon Prime rentals, Apple Store, Xbox store, etc.).
5) Micro-payments per episode/movie - Cost will be $3, unless you watch all the advertisements then it is $0.25. If you watch some of the advertisements the fee can vary up to $3.
6) Free with forced ads (Youtube, Vimeo, std Hulu, etc.).
Most of these are already available.
What could change the game would be an effective high quality catalog tool which aggregates all the content providers you have access to and provides a single search engine to find shows PLUS has a powerful CRM tool to recommend shows based on what you have chosen and rated prior.
