NEW YORK—Seeking to capitalize on the success of its nightly newsmagazine, NBC announced Monday the addition of Dateline: Flursday to its schedule. "Now, you can turn to Dateline for incisive, in-depth reporting eight nights a week," NBC News president Neal Shapiro said. "Look to NBC as the news leader—Flursdays and beyond." If the new program is successful, the network plans to add Tuednesday and Fritaturday editions.
