Synopsis by Hal Erickson
Mystery writer Jessica Fletcher (Angela Lansbury) is given the opportunity to solve her 286th murder, this one connected with a San Francisco fine-arts radio station. The station's ruthless new manager has elected to boost ratings by changing the outlet's image and format, and by firing a number of employees who are deemed too old for a hard-rock audience. So just guess who gets murdered. . .just guess! "Death by Demographics" is an ironic title for the final hour-long episode of Murder, She Wrote, which had been cancelled by CBS after 12 seasons and 264 episodes because it "skewed old" in the ratings.
