The Expanding Dick Wolf Universe: The FBI Spin-off "CIA"
The *FBI* franchise, created by the legendary Dick Wolf, is not just a single show; it’s a successful universe that includes *FBI: Most Wanted* and *FBI: International*. The latest and most exciting news for the franchise is the announcement and development of a fourth series: *CIA*.
The new spin-off, *CIA*, was officially ordered to series and is expected to premiere in December 2025.
