The program had a successful seven-week run at the end of 2013.
The cable network announced Wednesday it ordered an additional 13 weeks of the show starring popular comedian Pete Holmes.
New episodes of "The Pete Holmes Show" are to start airing Feb. 24. They will air Monday-Thursday nights at midnight, following "Conan."
"The first 28 episodes were a joy to make, and I'm so thrilled we get to keep going," Holmes said in a statement. "We have so much more we want to do, and I'm looking forward to the opportunity to make great comedy, continue to evolve the show and really push the limits of potty language and tasteful male nudity. I can't wait!"
