Forgive my ignorance, but why the delay? Is this "punishment" for not viewing it when it's broadcast? I mean, why wait more than 24 hours? If you are that much of a fan of a show, you're going to watch it when it airs, yes? And if you already have NetFlix, then offering it more quickly would just increase your chances of acquiring new viewers that might turn into fans who might just watch it when it airs. If you are already a fan, then it's just gravy in case you miss an episode. So where is the advantage to waiting?
Probably because they don't want Netflix to become a substitute for regular broadcast TV. If episodes were available on Netflix the day after they aired, why would I ever bother to watch the show live? Easier to do it on my own time and avoid ads. Ideally, these companies would rather you watch all their shows live, not on Netflix at some indeterminate point in the future. The 15 day waiting period is a compromise that lets Netflix subscribers view old shows and ones they've missed, but doesn't cut into the viewers who are wiling to work their schedules around live TV. It isn't "punishment" as much as they are trying to increase the total number of viewers without cannibalizing the broadcast TV market that they've leaned on for 50 years.
