A self-proclaimed computer geek has invented a new tech toy. It’s not for your average tech-savvy individual, but for the individual who doesn’t mind being a bit selfish and rude.

San Francisco resident Mitch Altman constructed a $15 keychain gadget that allows people to turn off most TVs anywhere from a bar to an airport. So, if someone doesn’t like what you are watching and he or she has the “TV-B-Gone” gizmo in his or her back pocket, it takes one zap, a 17-second delay and the TV will shut off.

Altman said he would never dare to silent TVs in places like sports bars, where people expect the boob tube to be on at all times. Good thing, because although he said he gets little or no reaction when testing it in some places, he likely would have an angry group of bargoers staring him down.

Just because no one made a scene when he discreetly tested the tiny remote in many places doesn’t mean that there wasn’t someone who would have liked the TV to be on. Those around were probably too freaked out that the TV just magically shut off to react publicly. Chances are, they didn’t assume there was some guy lurking around with a tiny remote control shutting off the TVs to evoke a reaction.

How rude can a device be? Unless no one else is anywhere near the TV, it’s unjustifiable for someone to think they have the right to turn off a TV while someone else might be watching. If people become discombobulated because of a TV, they should politely ask either the individual who is watching it or the business that the TV is in to turn it off. Taking it upon oneself to turn off a TV in a public place is flat-out rude.

Altman said he just doesn’t like TV, and he would like people to think more about the powerful medium in their lives. He hasn’t owned a TV since 1980.

Well, Altman, just because you don’t like TV doesn’t mean others don’t.
