The 2000s is the decade I first truly tussled with television. As such, it's going to get really challenging to narrow down (and even more so from here). Just rest assured that an honorable mention here is worth a ton more than some on the '70s list. That's because this is when television became sweepingly good, y'all! Comedies lean smarter, dramas become serialized, miniseries prove viable. The whole thing gets blown open across the landscape of stations. This list is also tough because in the example of 30 Rock, it's obviously an all-timer. But it splits its classics between the 2000s and the 2010s and therefore might not be an ace of either? We'll see. Either way, the field must expand to fifteen here.
Honorable mentions: Avatar, Planet Earth, The Wire, Daily Show, Friends, HIMYM, West Wing
