A DAILY YOMIURI article takes a look at the growing popularity (and expanding number) of late-night TV animated shows.
The number of such shows in late-night slots increased to 17 this season from 10 last autumn. Many of these shows are produced with viewers in their 20s and 30s in mind as producers hope to cash in on DVD sales of programs aimed at this generation.
All the good shows are definitely the ones that appear during that time period. Anything earlier is usually Pokemon-like crap.
