A 6% sales rise helped the brand continue its reign as king of the crisps in 2009, and Pringlesí 3% fall means the gap between the top two grows ever wider.
Pringlesí disappointing performance shows a raft of new flavours and limited editions, such as the introduction of Thai Sweet Chilli and Xtreme Firery Wasabi, arenít enough to guarantee an improvement in sales.
In contrast, itís been a good year for Doritos and although the brand hasnít matched or surpassed last yearís 17% growth, a solid 13% uplift should be cause for celebration at Walkers HQ.
McCoyís 4% drop might give United Biscuits cause for concern, especially as the brand had such a big marketing investment behind it last year. The company will now be hoping that reducing the brandís saturated fat content by a further 30% in 2010, and introducing a Bacon Sizzler pack and Sizzling King Prawn multipack, will begin to have a positive impact on sales.
Unitedís other top 10 brand, Hula Hoops, has also dropped by 1%, but the brandís link-up with Sports Relief could soon change all that, with an on-pack promotion and £1 million ad campaign kicking off this month.
Kettle Chipsí 6% growth might be modest compared to its performance in previous year, but, according to the manufacturer, it? still proves consumers want natural-tasting crisps made from real ingredients.
So what can explain Sensations 19% drop in sales? Itís hard to decide whether Sensationsí recent advertising has failed to resonate with consumers, or if a host of new innovative seasonal editions for Kettle Chips has stolen sales away from Sensations.
One thingís for sure though, if the brand continues at its current rate of decline it may have fallen off the top 10 completely by this time next year.
Wotsits sits at the bottom of the line-up and is up 10% despite it being a fairly quiet year for the brand in terms of ad campaigns or innovations.
