I have a funny story about the Blacklist. My wife and I started watching that show. We got through season 1 and we had our DVR set to record season 2. Turns out we set it to only keep 5 episodes and not all. So when we got time to watch it, it had deleted the first 3 episodes of season 2 and only had the next 5. But that's OK because NBC said you can catch up on missed episodes online. No you couldn't. They would only show you the most recent episode and maybe one or two others online. Which in our case were the episodes we had recorded. The rest were just the trailers for past episodes. So we ended up deleting the shows we didn't watch and never went back to watch it.
To this day, I still don't understand why networks (ABC, CBS, FOX, NBC) don't make their shows more readily available after they air. With streaming services letting you pick your episodes, why don't the networks do the same? Maybe they do now and I just haven't attempted to watch anything from the networks that fit this scenario. But this is an example of how they lost viewers because we missed a few episodes and couldn't catch back up. And unlike the streaming services, these networks rely on ratings and us actually watching. So if we miss and feel like we are lost, we are done and they lose viewers.
