Snack-a-Jacks, the sweet and savoury rice snack, is launching a four-week £1.2m TV advertising campaign, following the addition of two flavours to the range, Tomato & Herb and Vanilla. The ad positions the brand as a guilt-free snack between meals. The campaign breaks this week as a 30-second ad, and will be cut to 25 seconds next week, with a five-second tag featuring the flavours. Based on the idea that people have an errant 'Snackhand', the ad depicts a woman in a newsagent trying to control her hand as it clutches at sweets and crisps. The shopkeeper brings the fight to an end by offering her a pack of Snack-a-Jacks and the woman returns to her office. Creative is by Abbott Mead Vickers BBDO, with media by OMD UK.
