Birmingham-based digital agency Clusta has completed a series of new in-store TV adverts for Kelloggs to promote their new Special K Sustain product throughout the Tesco Screens network.

Clusta was appointed by marketing consultancy dunnhumby to produce the shorts, following a previous successful collaboration for the launch of Wrigley’s Extra Big One, which then saw a 25 per cent sales uplift. In separate news, Clusta has this month launched its first overseas office in Los Angeles, due to demand from American clients.

The LA branch is headed up by Clusta’s VP of sales and marketing, Sarah Kelly, offering graphic design, 3D animation, branding, web design, video and post production.
