Users don't "demand" ads of any sort, let alone Flash ones. Advertisers demand Flash-based ads, because they can do stuff like animation and sound, but more importantly because they can use Flash's full tcp/ip sockets to send arbitrary tracking information home (e.g. how long was the ad displayed for, any mouse-over events, browser and os information, etc).
