Long term, we'll probably wind up with a couple of major marketplaces that provide a UI that ties together content bundles that you've purchased from different distributors (who will actually serve up their catalogs). It's a bit depressing how similar that sounds to how cable networks work. Or platform specific app stores.

Just now I did a search for "all the presidents men." Top hit was "All The King's Men" but the right movie did show up second. It says "Not available for streaming, rental, or purchase. Click below to set reminders."
So I hopped around and did a few quick searches:
streaming on Netflix (i think) https://www.netflix.com/watch/243547
streaming on amazon (with Cinemax) http://a.co/605SHmD
for rent or sale on iTunes https://itunes.apple.com/us/movie/all-the-presidents-men/id5...
for rent or sale on YouTube https://www.youtube.com/watch?v=ZAGNFnI7mZ4
The page also says it's not for sale on DVD or Blu-Ray (showing an Amazon logo): http://a.co/aoa6bG8
