Whether you've wanted comedy (Curb Your Enthusiasm, Flight of the Conchords), glamour (Sex and the City), dark gloom (Deadwood) or just some sexy vampires (True Blood), HBO has had something for everyone.
AMC and Showtime may now be going head-to-head with hits such as Mad Men, The Walking Dead and Homeland, but HBO was the trailblazer and one of the first to truly prove the potential of small screen drama.
So crack open the champagne, tuck into some birthday cake and keep your fingers crossed for another 40 years with as much awe-inspiring telly.
