The Travel Channel and Food Network, which each ran an Anthony Bourdain show, have tweeted about the news of the chef's death.
"He was an incredible talent who showed us beautiful, gritty, complicated and delicious places in every corner of the world," the Travel Channel tweeted.
Food Network retweeted the Travel Channel's message, adding information for the National Suicide Prevention Lifeline:
First, he hosted "A Cook's Tour" on the Food Network, then moved to the Travel Channel with "Anthony Bourdain: No Reservations," a breakout hit that earned two Emmy Awards and more than a dozen nominations.
In 2013, both Bourdain and CNN took a risk by bringing him to the news network still best known for breaking news and headlines. Bourdain quickly became one of the principal faces of the network and one of the linchpins of its prime-time schedule.
