Jon Stewart has explained that he decided to quit US satirical series The Daily Show after 16 years because he was no longer getting "the same satisfaction" from it.

Speaking to The Guardian about his announcement last February, Stewart said that he had been considering his position on the show for some time.

"Life doesn't really work that way, with a finger pointing at you out of the sky, saying, 'Leave now'," he said. "That only happens when you're fired, and trust me, I know about that.

"It's not like I thought the show wasn't working any more, or that I didn't know how to do it. It was more, 'Yup, it's working, but I'm not getting the same satisfaction'.

"These things are cyclical. You have moments of dissatisfaction, and then you come out of it and it's okay. But the cycles become longer and maybe more entrenched, and that's when you realise, 'OK, I'm on the back side of it now'."

Stewart added that he has chosen to leave ahead of the 2016 US Presidential Election because he sees the American political system as "increasingly redundant".

"Honestly, it was a combination of the limitations of my brain and a format that is geared towards following an increasingly redundant process, which is our political process," he said. "I was just thinking, 'Are there other ways to skin this cat?'

"I'd covered an election four times, and it didn't appear that there was going to be anything wildly different about this one."

He also expressed a desire to reassure Daily Show that the series will survive without him because the content is more important than his presence.

"The value of this show is so much deeper than my contribution," he insisted. "If Oprah can leave and the world still spins, I honestly think it will survive me."
