Equiso

This is one of the newest devices for your TV and is awesome. Details can be found on kickstarter.

The Smart TV is an HDMI dongle (left bottom of pic) that plugs into your television and essentially turns it into an Android tablet. You have access to apps, the web, and any video content you can stream and store on the device. it lets you play free YouTube movies and any other movies from the web. You can check your email, including replying, etc.

It includes a portable keyboard and the remote shoots a beam that makes it act like you are scrolling with your fingers. It is coming out soon and the price is slated to be only $69. I love technology and this is soon to be in my living room.

Zenith Space Command

In 1956, the first widely used TV remote control had four buttons (power, volume, channel up, channel down) but no batteries. Press a button, and a tiny hammer inside the remote would strike an aluminum rod, transmitting an ultrahigh-frequency tone to control the set. They were affectionately known as clickers, because they actually clicked when you pressed the buttons.

Pictured remote outside and inside. Back then they only had a few channels to scroll through, and all TVs were black and white, so it was not a big deal.

I read that you could sometimes drop a coin on it and it would change channels. The Space Command lasted more than 25 years before being replaced by remotes using infrared technology. Before these slick devices, they actually had a remote that was physically wired directly to the TV. . . and before that they had kids that they would tell to go change the channel, or turn up the volume.
