Answer
The answer is Conan O'Brien, a prominent late-night talk show host. In 2010, O'Brien was embroiled in a highly publicized conflict with the legendary host Jay Leno. The dispute centered around NBC's decision to move Leno's show to O'Brien's time slot after Leno's primetime show failed. O'Brien's departure from NBC and subsequent lawsuit against the network marked a significant moment in late-night television history.
