Network TV executives want "hit" shows. That means a number of shows go on the chopping block every season because they under perform in the ratings. My many years in broadcast media have taught me EVERY system of measurement is flawed. Letter writing campaigns have saved shows from being axed before, and they will again. The original "Star Trek" series wasn't expected to last through its first season. The franchise still thrives more than 50 years later. One of your favorites may be "on the bubble." USA Today reports, 27 Shows are being considered for cancellation unless viewers save them. They include "Murphy Brown", "Splitting Up Together," "McGyver," "The Cool Kids," "Madam Secretary," and 22 more. Click here to see the complete list, and vote to save your favorite.
