Are they still making episodes of whose line is it anyway?

Yes, "Whose Line Is It Anyway?" is still being made!

* The original British version ended in 1998, but there have been several revivals and spin-offs.

* The American version aired from 1998 to 2007, then was revived in 2013 and is still going strong on The CW.

So, if you're looking for more improv comedy, you're in luck!
