After not being able to find a suitable online stream of this event (I don't have cable), I gave up and built a rudimentary antenna for my TV. Basically, I just wound a bunch of copper wire around a piece of cardboard and stuck it in the window. The other end of the wire went into the cable port on the back of my TV. Surprisingly, I was able to pick up the game in crystal clear, digital 1080p!

Antennas made of a straight bit of wire of about 1/4 the wavelength usually work well. Think FM radios: freq about 100 MHz -> lambda = c/freq = 300 cm -> antenna of 75 cm (30 in).

For the sake of clarity, could you explain the set up? How many channels could your copper wire pick up?

That's pretty impressive, mind sharing a photo with us? I just want to understand what this level of awesome looks like.

Before I signed up for cable, I built this and had pretty great reception. Just a couple of parts from Home Depot/Radio Shack and you're good to go:

Watching Watson's avatar gave a little insight about what the software may have been doing. The results, based upon that avatar. The % is its confidence in its #1 response.

The longer the question the longer Watson has to generate an answer. Isn't that an important advantage?

I'm not sure I understand your point. All of the contestants "see" the answer at the same time, and none of them are allowed to buzz in until the magic light goes on.

Thanks for the links. I love the bits when Trebek visits Watson in the lab - it's the sort of thing where kids in 20 years will giggle at the fact that their pocket computer is more powerful.
