Unity seems to keep investing on random webinar platforms,
this time its from https://www.on24.com/ (which apparently costs +10-50k usd or more…)
sure those kind of platforms promise all-the-stats™ and +9000% engagement, but its totally useless related to most of the unity webinar topics… (especially when the viewer is suffering from bad UX in all of those platforms)
in the meantime, twitch is probably only streaming platform that offers proper full screen + chat view in one window. (and you could easily have surveys and polls there also).
zoom has been used many times also, but video quality there is like 240x140 + compression… and often videos has stopped playing there for the presenter and other issues.
i mean look at this on24 design (yeah, you cannot resize those windows, only minimize or maximize full screen)
