I don't even know if you can get a season pass and I don't know a better place to point this out, although this could affect some other shows. According to my Roamio, NBC airs one hour of convention coverage every night at 10, Monday 8-18 through Thursday 8-21. It appears ABC and CBS have some coverage but in a lot of cases all I see is "To be announced", as if they want to change their minds later. I can remember when all three networks had the convention for the entire night. In fact, I seem to recall doing stuff on the floor during the day as a child while a convention was on.
