What are the details?
Kotb, who has been filling in for Lauer since his November firing, will take over in his former role as "Today" co-anchor, according to the network.
"It’s 2018 and we are kicking off the year right because Hoda is officially the co-anchor of 'Today,'" co-host Savannah Guthrie announced during the Tuesday airing of the show.
"This has to be the most popular decision NBC News have ever made, and I’m so thrilled," Kotb said.
"I’m pinching myself," said Kotb, who has also co-anchored the show's fourth hour alongside Kathie Lee Gifford since 2012.
Guthrie responded, "You are a partner and a friend and a sister, and I am so happy to be doing this."

Lauer, after his swift firing, issued a public apology and said that there were "no words to express my sorrow and regret for the pain I have caused others by words and actions."
Is there more?
NBC News Chairman Andy Lack revealed Kotb's appointment to NBC employees in an email Tuesday, according to CNN.
In the staff email, Lack celebrated Kotb, noting that she "seamlessly stepped into the co-anchor role alongside Savannah."
"[T]he two have quickly hit the ground running," Lack's memo added.
"They have an undeniable connection with each other and most importantly, with viewers, a hallmark of TODAY," the memo continued, and noted that Kotb was "remarkable" and the "center" of the show's family.
"She has the rare ability to share authentic and heartfelt moments in even the most difficult news circumstances. It's a tribute to her wide range and her innate curiosity," Lack added in his memo.
Kotb will also continue to co-anchor the show's fourth hour alongside Gifford.
