Hot Summer Lights Question

When did the practice of sitting down on the midway for this show become common place?
Last time we went, it seemed everybody knew to sit down for this show instead of standing up like a typical firework show. Are there signs I'm not seeing somewhere?

Well its what, close to a 25 minute show?.. I wouldn't want to stand that long. For as long as I can remember, people always sat on the midway. That is why the park has the midway closest to Iron Dragon separated with the queue rail so guests can still walk by while the show is going on.

People have been sitting on the midway for that show since it opened in 1995. With the focus on the screen, it doesn't seem unusual to me.
