Even if it's not nominated, the fact that it is on Broadway will help with the sales of amateur licensing alone. It's easier to get amateur licenses for shows when you're able to say that the show has been on Broadway.
Look at Newsies for example. When it opened up at Pappermill it was to be a test run for the amateur version of the show that Disney had been working on. It's moving to Broadway because it did well in Jersey. But, they will do better with licensing of the show simply because it was on Broadway. There are more licenses for shows that were on Broadway than weren't. And, it helps to be able to say that when your licensing out your show. No one in that regard cares how long its been on Broadway. Just the fact that it's been on Broadway period.
