Secondary channel

A television channel you watch only when your primary channel is on commercial.

A secondary channel must be picked out during the first commercial break of your primary show/channel, and it also must be back from commercials as soon as the primary channel goes to a break, thus avoiding the black hole of boredom caused by retardedly long commercials.

Guy 1: "Gosh darn it! It's on commercial again! Pick a secondary channel already."
Guy 2: "Way ahead of you." -click-
