The article doesn't really say why the decision came down the way it did. Without knowing the details I agree that it seems strange, as a TV channel and a phone platform don't seem easily confusable, however look at it this way: Sky is a broadcaster for transmitting video and audio to many people. Skype is a communication platform for transmitting video and audio between groups of people. With that description I can now see why Sky won the trademark case. I still don't agree with the decision, but at least now it doesn't seem so crazy.
