Why do series disappear at netflix?

Why actually

Because then new ones come. Does not always run the same on television or in the cinema.

What netflix did not produce itself, but bought it over, must be licensed over the time per market. If that is not worth it, it will fly out.

That's nonsense, of course, because netflix has nothing exactly to do with linear TV.

For the broadcast because the transmitter must acquire a license subject to a license, that is, one has only the right the series for z.b. To broadcast for 6 months.

Another reason is the artificial scarcity. A good is all the more begeherter more scarce, it is a strategy which is also used in discos or rollercoasters.

If a series is again a program, then you can advertise again: NOW AGAIN IN THE program

and the audience is happy.

Because the licenses expire.
