This year CBS is introducing its first schedule in 16 years without a CSI series as the venerable procedural franchise ended with the cancellation of the latest offshoot CSI: Cyber. But that may change. “We are incredibly proud of all CSI shows, CBS Entertainment president Glenn Geller said during CBS’ upfront press breakfast. “It may come back in another incarnation.”

I hear the producers of the billion-dollar drama franchise also have been open to revisiting it and, after a break, that may happen.

After an inauspicious start on Friday in fall 2000, the mothership series went on to become TV’s biggest drama series and helped CBS establish a foothold on Thursday. The original, which ended its 15-year run with a two-hour finale last fall, spawned three spinoffs: CSI: Miami, CSI: NY and CSI: Cyber.
