But.. to play devil's advocate.
Doesn't putting shows on TV and DVD negate what the whole LIVE theater going experience is ABOUT?
If you record/broadcast/make available to the masses right off the bad, you won't ever find an audience
If you record/broadcast/make available after the run is over, you won't gain an audience.
This is the "debate" most producers have when thinking about the timing of tours, making a movie version, etc.
And there are so FEW pro-shot full musicals that exist that I would call a GREAT representation of the show. Some are fun to watch and done decently - but nothing (with current technology) ever be able to recreate the experience of sitting in a theater with an audience around you as you see a not-always-flawless production.
Isn't that why we love going to the theater?
Who knows - maybe one day they'll have holographic technology that will allow people to watch a production digitally where you aren't dictated where to look by a director and a set # of cameras, but rather how one watches a show when in the theater.
Just some random thoughts...
