Lost exploded onto our screens with an amazing first season that had everyone talking.
2004 was also the year that House made its television debut, continuing the trend of British actors taking up American accents to land leading roles in the US.
A trend that was kickstarted by the still ongoing greatness that was The Wire. Possibly the greatest television show of all time.
HBO were killing it that year, with The Sopranos still running hot.
Curb Your Enthusiasm, one of the funniest shows of all time, was still providing us with plenty of laughs.
