I am 35 and largely for this reason I have personal experience of Australian television of the 1970s, experience which compensates with quality what it lacks in quantity.
I didn't get much memorable entertainment out of TV as an infant (Catweazle, The magic Roundabout, Aunty Jack, and The Goodies honourably excepted) but one TV thing I do remember with chilling, decades-annihilating clarity is the ad for Flake bars which has carved itself a dedicated and permanent fascicle among my neural pathways.
I'm sure you know the ad I mean. According to the person who uploaded it to Youtube, it hung around on telly for years and years, which sounds right. Nevertheless my memory of it dates very precisely from the era when the kitchen benchtop was at eye level and I was an adept at handling the Happy Hopper.
I believe that it was this ad taught me to experience the emotion of disgust. God, it made me feel horrible!
The ad goes like this: a woman dressed in white polyester flounces and carrying a white basket walks along the pillared and cluttered verandah of an inauthentically 'gracious' house and steps down onto the facistic-imperialistically green lawn. The whole thing is larded with Vaseline and aureoles, and on the sound track an invisible chinless wonder is awfully singing a song about having things done to you with flaky chocolate. Swinging her basket, which has a Flake in it (tastefully concealed under a peach polyester napkin), she walks to the shrubbery and seats herself in the seclusion of shady long grass under a tree. Meanwhile back at the house, a man also dressed mostly in white is sucking on a glass of Coolibah when he sees (or possibly smells) the woman walking away and a 'tally-ho' expression comes over his silly face. He puts a flaccid white hat on his head, which emphasises the unpleasant way his hair lies like a recently killed kitten on the back of his neck, and follows her down to the bushes.
She's sitting there poking suspiciously symmetrical fragments of Flake into her lipsticked mouth and he sneaks up behind her and pushes his head between the branches, triumphantly fingering his hat. She looks up at him from under her own hat and smiles while steadily continuing to mumble manicured rectangles of Flake. Yuk! I don;t know what's worse. She sneaked off to guzzle chocolate on her own and then he followed her in order to scab some. Have they no shame?
