Morning news viewers in various parts of the country will soon be able to watch more on CBS.

CBS News will launch a live, third hour of its flagship "CBS Mornings" AM program on September 30, a move that will extend the show to the 9 a.m. hour. "CBS Mornings Plus" will be co-anchored by Tony Dokoupil and Adriana Diaz, and will air weekdays on CBS-owned stations in Los Angeles, Chicago, San Francisco, Detroit and Miami and simulcast on CBS News 24/7, CBS News' free streaming news channel.

“This expansion of ‘CBS Mornings’ shows a commitment to the brand and I’m excited to see what this team can do with another hour of real estate to experiment with,” said Shawna Thomas, executive producer of “CBS Mornings” and the new expansion. “People say all the time that they wish we had another hour. Now it’s time for us to do something smart with the time that audiences will appreciate.”
