“This has to be the most popular decision NBC News has ever made,” Guthrie said.

Here’s what else you need to know about Kotb:

   She’s an Okie: Kotb’s parents are Egyptian, but she born in Norman, Oklahoma, home of the University of Oklahoma (no word on who Kotb was rooting for during Monday’s thrilling college football playoff game, which the University of Georgia won over Oklahoma in double overtime). The family later moved to Alexandria, Virginia, where Hoda was elected homecoming queen at Fort Hunt High School in 1982.

She got her first TV job in the Deep South: A graduate of Virginia Tech, where she studied broadcast journalism, Kotb said she worked her way down south towards the Florida Panhandle getting rejected at a number of TV stations. She finally was hired for her first job at WXTV in Greenville, Mississippi.

Kathie Lee and Hoda share a Coke, peanuts and a smile Friday on a typically freewheeling fourth hour of “Today”.

 She’s staying loyal to Kathie Lee: After working as a news anchor and reporter at top-rated New Orleans station WWL-TV for much of the 1990’s, Kotb became a correspondent for NBC News and “Dateline NBC” in 1998. She was nominated for multiple Emmys for her work on “Dateline,” winning in 2010. But she really became known nationally starting in 2007, when she and Kathie Lee Gifford teamed up as co-hosts of the rollicking fourth hour of “Today.” Kotb said Tuesday she would continue hosting the 10 a.m. hour along with Gifford, along with her new fulltime “Today” duties. And Gifford was thrilled — but not surprised — to hear it, telling “People” magazine, “She’s already the hardest working woman there.” She figured out a way to keep everything that is bringing great joy into her life and have this dream job.”

 She’s a breast cancer survivor: Diagnosed with breast cancer in 2007,Kotb underwent a mastectomy and reconstructive surgery. and she tried to use her ordeal to help others, allowing the “Today” show cameras to follow her for a story that ran during Breast Cancer Month that year.  She was declared cancer free in 2008, and earlier this year, she talked about what being a breast cancer survivor meant: “I have to say, if you survive breast cancer or anything, you get four words,” Kotb said on “Megyn Kelly Today” on NBC,  “and those four words are ‘You can’t scare me.’”

She’s a (relatively) new mom: Last February, Kotb called into the “Today” show with an unexpectedly delightful story: She was the new mother of an adopted baby girl. Well, unexpected to some people. Gifford joined Guthrie and Lauer on the “Today” set to “take” Kotb’s call. Not long after a photo flashed onscreen of Kotb cradling the infant whom she’d named Haley Joy, Gifford exclaimed, “Do you know how hard it has been to keep this secret? I’ve got the biggest mouth!”
