Yeah, I'm just disappointed. If the media had created a message around the diversity of Broadway and not just Hamilton, then Broadway and what people think about it could've really changed a lot. Broadway's audience has always been affluent, white people, and the stories shown on broadway have catered to them regarding the types of shows that are put on. You don't put on shows that don't target your audience and when the overwhelming majority of your audience is all one specific thing, then all the plays will be shows that cater to that one thing.
In 2014-2015, the audience census reported that black audience members are up to 6.0% of audience members (3.6 in 1998-1999 for reference) which isn't a lot but it's a start. They didn't report numbers for other groups (hispanic, asian, lgbt, etc) in the article I read. No doubt that number will be a tad, tad higher in the new reports because of Hamilton, but Hamilton tickets STILL were priced so high that only the affluent could afford it aka a majority white audience. If the media reported "Hey guys, if you want Hamilton tickets and aren't royalty, then sucks to be you, but here are some other great shows that offer just as much diversity for you guys to check out", then they could've made a huge difference in the audience make up and in turn, the stories that ended up on stage.
Eclipsed was barely promoted despite the creator being the actress who plays Michonne in The Walking Dead and one of the actresses being Lupita Nyong'o. Although not sure if that was just a limited run gig. The Color Purple and Shuffle Along are still playing but the media could've made an attempt to spotlight those if they wanted to - if they were truly interested in diversity and not just following the hype of a group of people (the fandom) and trying to capitalize on it. The media could've really helped shift the audience demographics and help continue to diversify stories/lead roles. They could've helped push people who aren't affluent to off-broadway shows that are cheaper. And could've pushed people who were a little more affluent, who can't get Hamilton tickets, to other shows. But I feel like most people just know Broadway as "stereotypical broadway plus Hamilton".
Obviously the results haven't come out yet and this is only speculation but I don't think Hamilton changed the audience demographics as much as it could've and I put part of that blame on the media, who pushed the "diversity" thing in a way they could profit from it, not in a way to help literally anyone else. There have been strides because of Hamilton but there could've been a lot more.
And that's my thesis of the week :)
Side note: The Glinda thing gets me every time. Wicked is a story, first and foremost, about discrimination based on the character's skin color. Yet they rarely take on non-white actresses for the lead roles. Astounding. Also, I'm not sure about Valjean, I believe Kyle was being touted as the first black Valjean on Broadway specifically. No clue about tours or West End Valjean's! What ever the opposite of a miracle is though, that's Kyle's story.
