30 Rock won 3 consecutive Primetime Emmy Awards for Outstanding Comedy Series. The series took the prize at the ceremonies honoring its first three seasons, in 2007, 2008, and 2009.
The first win came at the 59th Primetime Emmy Awards, when 30 Rock defeated defending champion The Office. At the 60th ceremony, the show completed a major comedy-category sweep: it won Outstanding Comedy Series, while Tina Fey and Alec Baldwin won the lead acting awards. The third consecutive series win followed in 2009.
The streak made 30 Rock the sixth show to win Outstanding Comedy Series three years in a row. The program continued to receive nominations in later years, including for its seventh and final season, but it did not extend the winning streak. This distinction is easy to confuse with the show's total Emmy success: 30 Rock received many additional nominations and won awards in acting, writing, casting, and other categories, but the consecutive Outstanding Comedy Series run itself lasted three victories.
