Primetime Emmy Award for Outstanding Drama Series

This is a list of winners and nominees of the Primetime Emmy Award for Outstanding Drama Series, since its institution in 1951. The award is often cited as one of the "main awards" at the Emmys ceremonies, and has changed names many times in its history. It was first called Best Dramatic Show from 1951 to 1954, then Best Dramatic Series in 1955 and 1956. In 1957, no specific award for drama was given, but in 1958 the category was split into two separate categories, Best Dramatic Anthology Series, and Best Dramatic Series with Continuing Characters with a winner selected from each category. The following year, the category was differently split into two separate categories, Best Dramatic Series – Less Than One Hour. In 1960, the name was changed yet again to Outstanding Program Achievement in the Field of Drama; this name was kept from 1960 to 1964. In 1966, it had its sixth name change to Outstanding Dramatic Series or Outstanding Series-Drama; this was used from 1966 until recently, when it became Outstanding Drama Series.
