The match eventually ends, even if it is not known in advance. When
all is said and done, it can be stored as X bytes on a video server
somewhere. It's broadcast is a Program Stream, which has no time
bounds, but recording it results in a Program.

Do you mean like soap operas? Each "episode" is a Program. The fact
that there is continuity in content is interesting information and
may form a basis for linking the Programs in an EPG or database, but
they are still individual Programs.

I agree. And, in my definition, a commercial is a Program (it's just
kinda short). The assembly of Programs, including commercial
insertions, results in a Program Stream.

There may be multiple content authors and they may span a long period
of time, and operate on each other's content. Not sure how to
capture this in the definition, though.
