As most people are by now aware, on June 12, full-power broadcast TV stations in the U.S. will stop broadcasting their analog TV signals and will only broadcast TV signals digitally. Obviously, that impacts people who have older TVs and still use antennas to get a TV signal at home. But what's not talked about as much is the thousands of portable TVs that will stop receiving signals once analog signal disappears for good. For those who rely on such sets to tune into sporting events, such as the NBA Finals, the analog switch-off requires immediate action.

It's no wonder, then, that the top two bestselling TVs on Amazon are portable TVs with digital tuners. The Haier HLT71 7-Inch Portable LCD TV sells for $105.99, while the Axion AXN-8701 7-Inch Widescreen Portable Handheld TV is $119.99. Coby's 8-inch TF-TV891 Widescreen LCD TV isn't as popular, partially because of its higher $159.98 price tag, but it still sits in the top 15.

So far we really haven't seen any digital portable TVs from tier-one manufacturers, which explains why all the top-selling portable TVs are from budget brands. We're still waiting for Sony's waterproof Bravia XDV-W600 to show up. (The 4-incher turned up in blogs late last year, but hasn't been heard from since.)

Anybody looking for a new portable TV? (Let's hope that all the old ones don't end up in landfills.) As always, feel free to comment.

The waterproof Sony XDV-W600 may be the future of portable TVs--but we're still waiting for it.
