Co-anchor Al Roker will contribute weekly video blogs that go behind-the-scenes at TODAY, introducing the people and places that are seldom seen by the public.

In his new weekly "Travel Detective" column, long-time TODAY contributor Peter Greenberg shares his travel secrets and answers viewer questions.

TODAYshow.com features four new topic sections, People, Participate, Travel and Pets. In People, viewers can focus on the guests and contributors that make "TODAY" so unique. Photos, interviews, and profiles are just some of the content in the new section. Participate provides a one-stop-shop for users to interact directly with the show and one another, via the blog, message boards, live votes and e-mail.

"We've remade the site to better express the personality and diversity of America's favorite morning media: 'TODAY,'" said Randy Stearns, MSNBC.com deputy editor. "We want to be a place where people can come each day to not only find the information they crave, but also to participate in an on-going conversation about the topics they care about most."
