I want to know the answer to the following question:
What is the TV drama 24 designed on?
All the background I'm provided with is that "A few of the notable portrayals of the FBI on television are the 1993-2002 series The X-Files, which concerned investigations into paranormal phenomena by five fictional Special Agents and the fictional Counter Terrorist Unit (CTU) agency in the TV drama 24, which is patterned after the FBI Counterterrorism Division.". Is that enough to answer the question?
