No, not those idiots on 'Top Gear', but those impossibly suave egotists who persuaded the world to spend its money from sleek offices in Madison Avenue. I have hung on every word, every gorgeous image of the four series shown so far on BBC4. And what now? Only that series 5 has been gobbled up by Sky Atlantic, so for me it's all over! Never mind that this new channel has been trailed by the likes of Dustin Hoffman - what a low blow for one whose favourite film is 'The Graduate'! I don't subscribe to Sky or its ethics. Well, kids, you know what I shall want for future Christmases - DVD boxed sets. How could I survive without knowing if Don continues with his charade; if Betty and Henry make a go of it; if Sally grows into a liberated woman; if Peggy gets her own ad agency. I love their brashness, their faults, their perseverance, and the way I feel at the close of each perfect episode.
