The medium of television has certainly never been stronger than it is today, to the extent that it's often difficult to justify a trip to the cinema when the world of TV can now maintain the same immersive, cinematic, artistic style. The premium production quality of shows on networks such as HBO and AMC has helped attract many of Hollywood's finest performers, to the point that TV is certainly no longer seen as the graveyard where washed-up movie stars go to live out their final days. This list celebrates the 30 greatest TV shows in the history of the medium, those shows that innovated and revolutionised small-screen entertainment, by way of outrageous, ground-breaking concepts, award-winning acting, and ambitious storytelling that toyed with the very idea of exactly what could or couldn't be talked about and shown on TV. Whittling this list down to 30 wasn't easy, but we've tried to include a little of everything: we've got timeless animation, classic sci-fi, shows that were unceremoniously cancelled long before their time should have been up, immaculate period drama, and even a show for kids. That said, there are certainly more than 30 amazing shows out there, so did we miss any of your favourites? Do you object to any of our picks? What about our coveted #1 spot?
