I'm not a great goer to shows, for various reasons. But it hadn't occured to me that they were primarily about taking part in competitions. A great deal is about shopping, it seems to me, plus looking at pretty games and, for some, trying a bit of participation gaming. Given we can shop online, there need to be lots of other aspects to make the financial and time costs of in-person interaction worth it. I suspect these are the bits that will be most impacted by social distancing, which will make it hard to open up again soon. If you think about, shows tend to be very crowded, with narrow walkways and crowds around tables and stalls.
