Mad Men

This is one you must see. As of this post all of the episodes over seven seasons are available for viewing on Amazon. Netflix has yet to put up the final seven episodes but all the others are there. 

The series is superb. Perfectly cast and produced, this smart scripted series is worth that portion of your life that will be devoted to it.This drama about one of New York's most prestigious ad agencies at the beginning of the 1960s, focuses on one of the firm's most mysterious but extremely talented ad executives, Donald Draper.

Created by and written brilliantly by Matthew Weiner. The series premiered on July 19, 2007, on the cable network AMC, and is produced by Lionsgate Television. After seven seasons and 92 episodes, Mad Men's final episode aired on May 17, 2015. Mad Men is set primarily in the 1960s, initially at the fictional Sterling Cooper advertising agency on Madison Avenue in New York City, and later at the newly created firm, Sterling Cooper Draper Pryce (later Sterling Cooper & Partners), located nearby in the Time-Life Building, at 1271 Sixth Avenue. According to the show's pilot, the phrase "Mad men" was a slang term coined in the 1950s by advertisers working on Madison Avenue to refer to themselves, a claim that has since been disputed. The focal point of the series is Don Draper (Jon Hamm), initially the talented creative director at Sterling Cooper and later a founding partner at Sterling Cooper Draper Pryce, and the people in his personal and professional lives. The plot focuses on the business of the agencies as well as the personal lives of the characters, regularly depicting the changing moods and social mores of the United States across the 1960s, starting Season 1 in March 1960 and moving through November 1970 by the conclusion of Season 7. Throughout its run, Mad Men received widespread critical acclaim for its writing, acting, and historical authenticity; it has won many awards, including 15 Emmys and four Golden Globes. The show was also the first basic cable series to win the Emmy Award for Outstanding Drama Series, winning in each of its first four seasons.[3] It is widely regarded as one of the best television dramas of all time.
