It all started with a note from a friend. I received an e-mail last week from a longtime buddy about video cables. Specifically, he wanted to know if RG-59/ RGB cable ever goes bad. If so, when should he replace it? It was at this point that I wished I worked for one of the fine cable manufacturers we all know and love. Maybe that is why he asked me, instead of one of the fine cable manufacturers. In any case, I rattled off the answer that I imagine most of you are thinking right now: Cable does not go bad.
