I think Roku needs to become a platform to grow.
A system where I have a single Roku account and simply add other services without having to have 37 different accounts.
That's something Amazon is already doing with their "channels" program where instead of going out and subscribing to HBO Now or Showtime Streaming, you subscribe through Amazon and they are activated wherever you get your Amazon video content and you are charged through your Amazon Prime account. The pricing is still too high for many of those channels, but it will take time to address that for big existing cable channels who still have contracts with cable service providers.
I hate to say it, but if Apple can own such a huge market for mostly very closed platforms (iOS, Mac, and the Music store), then Amazon could do great without supporting relatively niche platforms which the majority of the market do not recognize.
My point was that the Roku IPO success suggests there are a ton of investors who think they are the early winner in streaming entertainment services. Maybe they can take all this money they just received through this stock sale and invest wisely and leap so far ahead of Amazon, Apple, Google, Sony, and all the others that they do indeed justify the stock price. I seriously doubt it, though. Apple, Amazon and Google, at least, have multiple entertainment relationships with the content creators which allows them to leverage music and movie licensing alongside streaming content. Heck, I am impressed that my Amazon Fire TV devices allow me to search for any show on any service and it will open the app and start the show regardless of where it resides. I don't have to memorize which platform is showing the show I want to watch, I just need to remember the name. Neither of my Roku devices did that well, though it allowed searching, it didn't include every streaming service in the results and I could not start the show from the search results screen.
We'll see. I just think this is an example of an early dot.com bubble issue in streaming services which are years away from stabilizing.
