Two elderly ladies had been friends for many decades. Over the years they had shared all kinds of activities and adventures. Lately, their activities had been limited to meeting a few times a week to play cards.
One day they were playing cards when one looked at the other and said, "Now don't get mad at me... I know we've been friends for a long time... but I just can't think of your name! I've thought and thought, but I can't remember it. Please tell me what your name is."
Her friend glared at her. For at least three minutes she just stared and glared at her. Finally she said, "How soon do you need to know"?

TV camera zoom lens

In 1947, the first zoom lens for the television camera was demonstrated by the National Broadcasting Company in New York City. Previously, moving into a closeup shot required moving the entire camera toward the actor or object, or away for a long-distance shot. Now the same zoom effects could be produced using the Zoomar lens, which revolutionized TV sports. It was patented as a "varifocal lens for cameras" on 23 Nov 1948 by its inventor, Dr. Frank Gerard Back of New York City. His company, Zoomar, continued to develop his technologies into the 1970s, with optical innovations for television and motion pictures, as well as astronomical, medical, commercial, and even military applications.«[Image: Dumont camera with Zoomar lens extending over two feet from its front, c.1950's]
