According to CBS, Person of Interest received the highest test ratings of any drama pilot in 15 years, what one CBS executive called "crazy broad appeal you don't usually see." The ratings prompted CBS to move CSI, which had occupied that slot for over 10 years, to Wednesday 10/9c to make room for Person of Interest.-Washington Post
From the official CBS webpage-
PERSON OF INTEREST stars Jim Caviezel, Emmy Award winner Michael Emerson and Academy Award nominee Taraji P. Henson in a crime thriller about a presumed dead former-CIA agent who teams up with a mysterious billionaire to prevent violent crimes by using their own brand of vigilante justice.
Reese's (Caviezel) special training in covert operations appeals to Finch (Emerson), a software genius who invented a program that uses pattern recognition to identify people about to be involved in violent crimes. Using state-of-the-art surveillance technology, the two work outside of the law using Reese's adept skills and Finch's unlimited wealth to unravel the mystery of the person of interest and stop the crime before it happens. Reese's actions catch the attention of the NYPD, including homicide detective Carter (Henson), and Fusco (Kevin Chapman), a cop who Reese uses to his advantage.

Abrams and Bryan Burk ("Lost"), Academy Award nominee Jonathan Nolan ("Memento"), David Semel ("Heroes") and Greg Plageman ("Cold Case") are the executive producers for Warner Bros. Television.
