This is the first of my Face Palm posts.  In these I'll discuss claims -- almost always Marketing claims -- so divorced from reality the only adequate response is a Face Palm.

Years ago a fun, parody publication, "The Journal of Irreproducible Results", featured a learned article on the recent invention of the Darkbulb.  The Darkbulb, in one practical implementation, looks exactly like a normal Lightbulb.  Except, when you screw it into the socket and turn it on, it ABSORBS light instead of emitting it.  With enough Darkbulbs, of sufficient wattage, you could plunge any size room into inky blackness!

I often think of the Darkbulb when I run into Marketing verbiage to the effect, "Our HDMI Cables Produce Blacker Blacks!"
