NBC is shaking things up in the news department as it seeks a new feel for “Dateline” while also putting together a new magazine show to be led by Brian Williams, TVNewser reports.

Kate Snow, who has been reporting for “Dateline,” will have a new job at the network, having been named the second official correspondent on Williams’ one-hour, prime-time show, the story says. As we reported earlier this week, Harry Smith was named previously as a correspondent for the program.

Before she joined NBC, Snow was a co-anchor on the weekend edition of ABC’s "Good Morning America." She has had a number of jobs at NBC, including subbing for Williams as anchor of “Nightly News.”

According to NBC, "Dateline," which is in its 19th year, will be undergoing significant changes. Episodes are now devoting an entire show to a single case, following the formula set by CBS’s "48 Hours." In addition, Ann Curry might be leaving "Dateline," where she’s the current anchor, to concentrate solely on her co-anchor duties on "Today."
