Kuma is a japanese mascot/net character where Pedobear is based from.
Anarog-analog
so it's something to with the antenna I suppose
Way to put the pieces together.
Anaroguma, or roughly translated "Analog Bear" is a marketing mascot in Japan in conjunction with Chidejika (roughly translated Digital Deer) as part of the campaign to maket the switch to all digital broadcast in that area will fill finalize in 2011.
If you search Chidejika, you'll even find some art pieces of Anaroguma being beaten up by Chidejika, implying that Digital is taking over analog.
Pedobear on the other hand is a deviation of the popular 2chan character Safety Bear.
