At the beginning of the digital transition, TV stations were broadcasting both analog and digital signals. Since the VHF band was mostly filled up, that meant the digital had to be broadcast on the UHF band. Once the analog was shut down many stations moved their digital broadcast down to the VHF band. About 1/4 of the full power TV stations in the U.S. are broadcasting on VHF. The UHF band used to go to channel 69 but presently it ends at 51. I don't think the TV band will fill up any time soon. Digital broadcast actually freed up many channels. During the analog years you could not have adjacent channels in the same market. For instance, there could not be a channel 10 and channel 11. There had to be a gap between channels. With digital, adjacent channels are permitted.
