the amount of "niche" hilarious/awesome/interesting video on YT and other video sites is a huge factor (along with blogs and HN/Reddit-like sites) why I don't watch traditional TV anymore. It tends to be better, I'm not forced to watch ads, it tends to be edgier/uncensored, it's more personal and interactive, and it's also more asynchronous and on-demand, easier to time-shift, place-shift and device-shift to suit the moment.
