Comedy Central said Tuesday that in separate agreements, Stewart agreed to host "The Daily Show" through June 2013 and Colbert will stick with "The Colbert Report" until the end of 2012. The two shows air in the 11 p.m. Eastern to midnight block.
The contract extensions were announced a week after Conan O'Brien said his home after a short stint at "The Tonight Show" will be cable channel TBS. He will host a late-night show later this year that will compete with Stewart and Colbert.
O'Brien left NBC after the network sought to move him and "Tonight" to make way for Jay Leno's return to late night.
