In July 1997, HBO premiered its first one-hour dramatic narrative series "Oz", centering on the inmates of the Oswald State Correctional Facility, a fictional level 4 maximum-security state prison. The program helped start the trend of narrative dramas incorporating gritty realism and storytelling that became standard among premium cable services to the present day. While "Oz" was critically acclaimed throughout its six-season run, it was not until "The Sopranos" premiered in January 1999, that the network achieved widespread critical success with an hour-long drama series. "The Sopranos"—centering on mob patriarch Tony Soprano (James Gandolfini) and his family—received 111 Emmy nominations and 21 wins over the course of its six-season run, including two honors for Outstanding Drama Series. The mob drama's first wins for Outstanding Drama and Outstanding Supporting Actress in a Drama Series (for Drea de Matteo) in 2004, two of the four Emmys it won that year, marked the first time that a cable program won in either category over a program on one of the major broadcast networks.
