From Tony Soprano to Selina Meyer to Curb Your Enthusiasm’s secret weapon Leon Black, some of the most iconic characters in TV history originated on the airwaves of HBO. Since the heyday of New Jersey mobsters, Baltimore drug dealers, and Los Angeles undertakers, HBO has been the home of prestige television. Any TV enterprise lives and dies by the strength of its characters — audiences will only come back week after week to see characters they love — and HBO has plenty of unforgettable characters in its rogues’ gallery. This is the network that gave us Larry David.
