Piers Morgan announced Tuesday on Twitter that he has left CNN. The British broadcast journalist shared the news in a series of tweets, explaining he has decided to “try pastures anew.”

The 49-year-old journalist previously hosted the evening show “Piers Morgan Live.” After nearly 40 months on the air, it was canceled in February. In its last broadcast on March 28, Morgan thanked his audience, "even those who implacably disagreed with me, or just found my funny accent annoying," he said. In the meantime, he stayed with CNN, writing regular columns for the network’s website.

According to Morgan’s tweets, CNN Worldwide President Jeff Zucker offered him an opportunity to do 40 “big interview ‘specials,’” but after much thought he decided not to accept it.

Morgan has a strong presence on social media, but not everyone is a fan. A new study for the Sunday Times revealed he is the most trolled British celebrity: More than 8 percent of the tweets sent to him are considered abusive or offensive. But Morgan certainly makes it easy for his critics to attack him: He is known for starting  Twitter wars with celebrities and unleashing the occasional Twitter rant.

In his final tweet about his break with CNN, he calls out the National Rifle Association – a group he regularly criticized on his show. He made a similar remark in February on Twitter.
