The American journalist has joined Yahoo to anchor an expansion of the Internet company's video news coverage. She hopes the move will help persuade other broadcast TV veterans to delve into the online digital world.
"I am particularly excited about hopefully attracting other people to this platform and venture," Couric told The Associated Press. "We are in a major transformative time in terms of media in this country."
Couric will juggle her new role at Yahoo and continue to host her daytime talk show, "Katie" on ABC.
"I will be involved in developing a lot of concepts, but not necessarily doing everything," Couric said. "I will be doing interviews, but not on a daily basis. Probably monthly at this point."
Yahoo CEO Marissa Mayer has been trying to make Yahoo's services more alluring by bringing in well-known journalists.
"News is a definitive daily habit for our users, and Katie will work with our talented editorial team to pioneer a new chapter of digital journalism," Mayer said.
After making her mark in local television news, Couric went on to become a star on "The Today Show." Years later, she took over the anchor chair at "CBS Evening News," becoming the first female solo anchor of weekday network evening news broadcast.
She left "CBS Evening News" in May 2011 after five years on the desk to host and produce her nationally syndicated one-hour daytime talk show on ABC.
