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.
