Who developed the original Dexter TV series for television?

Who developed the original Dexter TV series for television? James Manos Jr. developed Dexter for television.

Manos adapted Jeff Lindsay's 2004 novel Darkly Dreaming Dexter for Showtime. The television version retained the central idea of Dexter Morgan, a Miami forensic blood-spatter analyst who secretly murders killers, but developed its own continuity, supporting cast, and long-running mythology.

James Manos Jr. is credited as the series developer and wrote the pilot episode. Michael C. Hall starred as Dexter, while Julie Benz, Jennifer Carpenter, David Zayas, and other performers helped establish the show's ensemble. The original series premiered on Showtime in 2006 and ran for eight seasons through 2013.

The main point of confusion is the distinction between developing the series and serving as a later showrunner. Daniel Cerone, Clyde Phillips, and Scott Buck were important writers or executive producers at different stages, but they are not the original television developer. Phillips, for example, served as showrunner during the early seasons, while Manos's credit belongs to the show's creation and pilot-development stage.
