Not everyone wants to binge a show from start to finish

Then don't.

Went to Netflix to watch at started on episode 1. From what I hear season 1 isn’t the greatest. I got through a couple episodes and then thought to myself, this is going to take so many nights of watching to watch them all in order. Never watched another again.

Here's a list of some of the most popular episodes of the office. I'd probably just pick one of the early seasons and go from there.

Now if I could turn on the television and say S6EP7 was playing I’d probably enjoy watching it.

Sure. But you can just watch that one straight out. Why simply hope that's the one Hulu decides to stream at a given moment?

Channel 1 is having a Harry Potter bingeathon. I catch it on episode 3 and continue to watch it.

There's definitely an appeal to rediscovering old classic movies. But in my experience, the amount of crap out there far outweighs the amount of gold. And the purpose of running channels isn't to give you a steady diet of quality show. Its to run what's cheapest to run at any given moment.

You only start seeing Harry Potter on the Daytime Movie Channel when its completely fallen off people's radars and the rights are cheaper to acquire.

You're far less likely to see Channel 1 having a Harry Potter bingeathon than you are to see them showing Gremlins or Home Alone, because these series are far cheaper to fill non-prime air time with.
