^^ Actually, the whole point is to drum up business and word of mouth for the show. Naturally, the assumption is that the winners will spread the word of mouth about the show they wouldn't be able to see without the lottery's cheaper tickets. But how do you maximize the possibilities of this concept?
Well, if you have 100 people who go to theatre for 20 seats, you have a smaller crowd, who generally have planned this part of their day and, upon losing, will go about the rest of their night and maybe try again another day or maybe not. But if you have a digital lottery, one that perhaps (like some do) you can double or triple your chances for by sharing news of your entry around on social media... well suddenly you have a larger, more vocal share of attention and free publicity going around regardless of whether these people win or not. More people know about the show and the lottery, and the more people enter the more their friends' know and so on. How quickly have any of our Facebook feeds become inundated with posts about the HAMILTON lottery?
It's a pretty blatant (but blatantly successful) marketing tactic. It works. It's likely the future. And it's extremely convenient, effort-wise, with less success results-wise. Shows are perfectly fine with that bargain, and so long as they keep offering lotteries we'll keep playing them. Because it's still a great deal if you win.
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
