From what I can tell, typically, for movies, the chronological release order is something like:

Cinemas » DVD » BD » aired on free-to-air (FTA) TV

Seems to make sense to me - people who want to see it first pay to do so, and the people who really want to see it forgo having their own copy of the movie.  After that, it's aired on FTA TV for everyone else.

For TV series:
aired on FTA TV » DVD/BD

I guess it makes sense to air a "TV series" on TV first, but ignoring this naming convention, it's interesting to note that it seems to be a bit of a reversal of the process for movies.

Discuss.
