Was President & COO of NBC (from 2001 to 2003), but stepped down in
2003 to take the Chairman & CEO post of Sony Music Entertainment. His
old colleague, Howard Stringer, with whom Lack worked with at CBS News
in the early 1980's wooed him away from NBC. However, some speculate
that Lack and NBC Chairman & CEO, Bob Wright, did not get along and
that there was a lot of tension between the two of them.
