Shadows, produced by Growling Dog Productions for butv10 at Boston University, is an ongoing episodic television series with a gothic science fiction theme. Created in 1995 by David Kalbeitzer and Pilar Flynn, this sci-fi/supernatural thriller is one of Growling Dog's flagship programs, the others being Bay State, BU Tonight, Overexposed and Inside Boston. Over 50 half-hour episodes have been produced since its debut, with Growling Dog continuing to produce one or two episodes per semester.

Dormant for several years, the show was revived in 2002. When production problems threatened the show's future, the production team decided to restructure the series, ending the serial plot lines that began in 1995. In 2005, the new format for Shadows premiered on butv10. Featuring single camera film-style visuals and a grittier, noir-ish texture, the new series focuses on a clandestine private detective firm, called simply "The Agency," run by the mysterious Jakob Resh.
