I hope they consider airing the older shows during the day as well, or at the very least sometime before 9-10:00 PM (i.e., "bedtime"). I don't deal with the idea that only older viewers are interested in older shows. I think The Hub should give these shows a chance. I don't know about anyone else, but to me, it doesn't matter when a show is made as long as it's a good (if not necessarily great) and interesting show to watch. Also, when I say older shows, I mean the animated ones to be exact (all two of them at the moment). That said:
Live action sitcoms are one thing, but when animation is involved, that changes the rules, IMHO. I'm personally willing to give the original TF and G.I. Joe series a try if they were to air them either during the day or just before bedtime hours. Those, and any other classic animated shows they decide to pick up. I don't really like the idea of not being able to watch a show I might like simply because it's past my bedtime...
EDIT: I forgot about Fraggle Rock. That's an older show, and that's airing during the day. However, I still hope they'll consider shows like the aforementioned original TF and G.I. Joe series and others for airings during the day (or at least before bedtime).
