Now that you mention it, yeah. I remember my mom doing the watch this microwave thing boil a cup of water demo for months everytime someone stopped by. It was a show. The last one I remember like this, with both "I want to show" and "I want see" high demand like that, was the Siri launch. Someone in my office got it running and he had people coming to his cubicle all day asking to hear it.

Last time I saw it was a guy bringing a VR headset to the office. Some 8 years ago.
