What about the radio?!

I've just been watching one of the recent episodes of NASAcast - Beyond the Light (MP3: 1.2 MB) - about the Chandra X-ray Oservatory (sic). Just under half way through, the presenter said "Astronomers examine the Universe through mainly four forms of light; gamma, visible, infra-red and X-ray light". What?! Does NASA think there is no radio or sub-mm astronomy? Do Arecibo, Greenbank, Effelsberg, Jodrell Bank, Parkes, WMAP and the rest not exist? Even though the video does then show (although doesn't describe) a radio image, this shows the wavelength bias of the people that made the video. I would have expected better of X-ray astronomers and I would have preferred slightly quieter, and less anxious sounding, background music too.
