A lot of surprisingly large markets had to make do with cable or LPTV coverage of the last two English-speaking "weblets" that grew up in the 90s. Rochester, NY, a TV market with about a half-million TV homes and over a million people in the metro, had the traditional big 5 served by full power outlets (3 Vs for the traditional big 3 of ABC, CBS and NBC, a high-powered U each for Fox and PBS). But the WB ran on a cable-only channel, and only got that because it was under common ownership with Time-Warner Cable. UPN had to make do with a low-powered U that barely covered the city of license, which eventually wormed its way onto the cable after several years of operation. Today in the digital age the big 5 still get full power signals while CW is a subchannel of the ABC affiliate (a full power V) and MyNetwork is making do with the same LPTV signal that used to carry UPN. If you're among the 25% of households in the market that depend on OTA signals, your menu for TV choice is no bigger than it was in 1986. I suspect the choice in other cities for those without cable or a dish is thinner still. And let's not even talk about the viewer whose native language isn't English, because cities like ours have never had a Telemundo or Univision over-the-air signal at hand, and half the country is probably in the same boat.
If it's true that the FCC is going to squeeze heritage VHFs back onto their old channels and put a lot more stations closer together on the band to open up space for wi-fi and broadand, let's hope they put a little push toward enocuraging more stations to use their subchannel capacity not to squeeze existing stations into a smaller space, but provide carriage in their markets for previously unavailable program services.
