Lack joined NBC as president of its news division in April 1993 and has turned "Dateline" into a four-times weekly franchise, with one night even going up against the venerable "60 Minutes." During the 1996-1997 season, with three "Datelines" shows per week, NBC boasted it was the most watched newsmagazine on the air (combining the total audiences for the three nights). However tabulated, the show although not initiated by Lack, became NBC's first successful primetime newsmagazine under his administration. Lack has also guided the growth of NBC News in Asia, and the NBC SuperChannel, the largest general-programming TV service in Europe. In July 1996, Lack added responsibility for MSNBC, with programming that included a nightly newscast hosted by Brian Williams, as well as related Internet services.
