^Because we didn't have BBCAmerica back then. In the Tom Baker days, we only saw it because local PBS stations aired it--usually at some strange hour, like very late on Friday, or in the middle of Saturday afternoon. But now that BBCA is on many, if not most, regular cable services, it's available to a huge audience. It's no longer just a strange kiddie show from England on some odd little channel; it's now a family adventure Sci Fi/Fantasy show on cable. NuWho's popularity has grown steadily and has really hit the heights with Smith. There's also a lot more media attention, especially after Who topped the iTunes list for the first time.
