TBS has officially cancelled comedian George Lopez's "Lopez Tonight" show and will not continue with its third season. The program, which airs after Conan O'Brien's weeknight talk show, will air its final installment on Thursday.

This all seems so familiar, as we are reminded of what happened to O'Brien's own show with NBC. 

In 2004, NBC came to a contract agreement between both Jay Leno and Conan O'Brien that the latter would replace the former as the host of "The Tonight Show" in 2009 in order to prevent O'Brien from moving to another network. 

However, since Jay Leno was still getting good ratings when the time came to transition, NBC didn't want to take the risk of losing those viewers to another network. As a result, NBC created a new talk show for Leno at 10 p.m. and Conan took over "The Tonight Show."

But Leno's 10 p.m. show didn't do so well, causing affiliate stations who relied on high ratings to carry over to their news broadcasts at 11 p.m. to bring in advertising revenue. Under the pressure, NBC decided to move Leno back to 11:30 p.m., and in turn, moved O'Brien's show to after midnight. 

O'Brien protested, feeling that the value of the Tonight Show brand would be impacted if it were move past midnight and threatened to quit if he had to move. To settle the controversy, NBC paid Conan and his crew $45 million to buy them out.

Following Conan's departure from NBC, he quickly signed a contract with TBS. 

The irony of the story is that George Lopez already had a talk show in TBS at 11 p.m., and the network bumped Lopez to midnight to put O'Brien at 11 p.m.

And now we learn that George Lopez has officially been cut.

O'Brien basically did to Lopez what Leno did to O'Brien, but not intentionally. Lopez was reportedly getting ratings that were below par, and his show allegedly was no longer profitable. Nevertheless, it's ironic how all this played out.
