I'm all for this. An early example of this (also pioneered by Fox) was Summer programming. While everyone else was in reruns, Fox was putting out new content during the Summer months (The OC, Glee). Not only did it bring strong ratings, it gave critics something to rave about because there was nothing else to watch or rave about, so no competition, at the time. I also liked it because the 3 months within Summer allowed for a straight run of all new episodes. This often worked well for mid-season replacements with 13-episode orders as well (Buffy the Vampire Slayer premiered in March, allowing for the first season to finish in May so the next batch would be ready to go in the Fall).
