Cloo

Cloo (stylized as cloo), formerly known as Sleuth, was an American pay television channel owned and operated by NBCUniversal which aired programming originally dedicated to the crime and mystery genres, though it often fell out of this format in its later years with a more generic selection of series and films, and was used as an example of channel drift and superfluous channel bundling, presenting series easily found through other venues. The channel launched on January 1, 2006, replacing Trio. It ceased broadcasting on February 1, 2017.

As of February 2015, approximately 25,495,000 American households (21.9% of households with television) received Cloo, though this declined with later removals by several cable services as carriage agreements expired.
