Shows Run: NCIS (2003-Present), NCIS: Los Angeles (2010-Present)

No, we don't watch either NCIS show, but the rest of America sure does. Not only do both shows regularly net in the neighborhood of twenty million viewers, both shows have steadily gained eyeballs over the life of the show, as in more and more people are watching. The flagship NCIS has seen their viewership double during its ten year run.

It was announced last year that we can look forward to yet another NCIS show. Start an office betting poll as to which city it crashes this time.
