Thanks to the (albeit fairly recent) propagation of superfast ADSL net service in Japan (how does $40/month for 50mbit/s sound?), there is a lot of net-only TV content... the wife watches cooking shows, and there's a great site explaining all the diseases your baby could possibly get.
Of course, this is nothing really new in the porn circles.. they're always the first to the gate in any new tech paradigm... there's piles of net-only porn... er.. so a friend told me...
