Netflix is still "competing" with discs at this point, although I would accept that discs aren't exactly winning. Most of the content I watch comes from blu-rays, and with a few exceptions (The Americans, grr), most of the things I want to watch have been released on disc. In fact, there is a small community of film enthusiasts who continue to purchase media outright, e.g., https://www.blu-ray.com.

I started using Netflix in 2001 as a DVD subscriber. It was wonderful for nearly 20 years. I ended up canceling before the service officially ended because it was clear that the writing was on the wall and the service was going downhill fast. You used to be able to get nearly any movie or TV series, domestic or foreign. It's a lot more work to find good stuff now, even with streaming in the mix.
