CBS is planning to launch a one-minute-long "microseries" that will air during one of the commercial breaks in the 9:00 pm. hour every night of the week beginning Jan. 24. The series, titled The Courier, will be sponsored by GM's Pontiac division, and, according to the Wall Street Journal, "tells the story of a mystery man who races against time to uncover clues and rescue his kidnapped wife." The series is reportedly aimed at viewers who skip commercials with TiVo and other digital recording devices and also, because each episode will end with a cliffhanger, to draw viewers to sample the network's 9:00 p.m. programs.
