Nina Tassler was named Chairman, CBS Entertainment, in February 2014. She reports directly to Leslie Moonves, President and CEO, CBS Corporation.

In her position, Tassler leads the Network's entertainment programming for primetime, daytime and late night, as well as program development in all genres, including comedy, drama, reality, specials and long-form.

In addition, Tassler oversees Entertainment division matters in advertising and promotion, business affairs, consumer products, digital/interactive, diversity, publicity, scheduling and research.

Under Tassler's leadership since she became President of the Entertainment division in 2004, CBS has been America's most watched network for 10 of the last 11 years.
