Okay some techno-speak. Skip if you are not interested.
The old TV standard was call NTSC, named after the National Television System Committee. The new standard is called ATSC, named after the Advanced Television Systems Committee. No one is the US or Canada is permitted to transmit NTSC.
ATSC use much less "spectrum" to transmit many more channel. Think of "spectrum" as how many "lanes" are reserved to TV transmission. NTSC was sloppy, so "empty lanes" in between were required. Even though the lanes are still the same width, ATSC can get 3 channels in that lane and there is no need for an empty lane in between. This is also why the new antennas are so much smaller.
In NTSC, channel numbers were related to a specific frequency (which lane) In ATSC, channel number or only for humans. Channel 2 may be the right most lane in you area and the left most lane in my area. Part of the incoming signal tell your TV what chanel number it is, irregardless of the frequency.
The government (FCC) has taken back many frequencies and will likely reclaim more. These are redistributed for different purposes.
Cable is a whole different story.
