Many general interest premium channels also produce original television series. Due to the aforementioned leniency in content standards, they too can contain content that is more mature than those of other cable channels or television network. These series also tend to be high-budget and aim for critical success in order to attract subscribers: notable premium series, such as HBO's "Curb Your Enthusiasm", "Game of Thrones", "Sex and the City", and "The Sopranos", and Showtime's "Dexter", "Homeland", and "Weeds", have achieved critical acclaim and have won various television awards. Some premium channels also broadcast television specials, which most commonly consist of concerts and concert films, documentaries, stand-up comedy, and in the past, theatrical plays.
