10 years ago today, on 19 July 2007, iconic TV drama Mad Men first aired in the US. It was the first glimpse we got of the mysterious advertising creative Don Draper (John Hamm) and the bonkers going-ons around him in his work life and love life – all of which overlapped on a regular basis.

90 episodes, 16 Emmys, 5 Golden Globes and one man’s tale of boozing, schmoozing and the occasional bit of work on Madison Avenue later – the show came to define the Second Golden Age of TV alongside The Wire, The Sopranos and Breaking Bad.

As the show celebrates a decade since its first airing, we’ve dug deep into the Mad Men canon to give you the definitive ranking of the show’s finest episodes. Bottoms up, here we go.

10. The Other Woman (Season 5, Episode 11)

Male characters’ escapades dominate most of the early episodes but as the show progressed, copywriter Peggy Olsen (Elisabeth Moss) and office manager Joan Holloway (Christina Hendricks) become integral to the show.

The Other Woman is the perfect example of the pair simultaneously making moves in the career. Joan negotiates a promotion and partnership in their company SCDP (Sterling Cooper Draper Pryce) – even if it comes at a pretty disgusting price and Peggy announces to Don that she would be leaving SCDP to join a rival firm. It’s not an ideal scenario for either character, but gives the two of the show’s most crucial characters the spotlight they deserve.

9. The Gypsy and The Hobo (Season 3, Episode 11)

Early on, it’s made clear Don’s identity crisis is show’s primary narrative, but it’s not until Season 3 that his true transgressions are made known to his wife, Betty (January Jones). Here she discovers the true extent of his identity theft, and his previous life known as Dick Whitman. Emotional and eye-opening for everyone involved.
