Two private detectives were do...

Two private detectives were doing some research on a scandalous divorce case in LA. At the husband's request they staked out the wife's bedroom, and sure enough, she had another man inside. The detectives remarked to one another that they were going at it as if sex was going out of style.
After watching rather furtively for quite a few minutes, one detective finally said, "As long as we’re here on the case, may be we should go in after him?"
To this the other replied, "Great idea! Who first?"

Video recorder

In 1956, the first practical commercial black-and-white video recorder was demonstrated at a broadcast convention in Chicago and simultaneously in Redwood City, Ca. The VT-100 by Ampex Corporation of Redwood City was the size of a deep-freeze with an additional five 6-foot racks of circuitry. The 2-inch wide magnetic tape moved at a speed of 15 inches per second. The system had four heads on a disc rotating perpendicularly across the width of the tape, thus tracing an oblique track pattern. A single 14-inch reel could carry a 65-min. recording. The Columbia Broadcasting System purchased three of the video recorders in 1956, priced at $75,000 for each unit, and first broadcast from tape on 30 Nov 1956.
