The product introduction – the largest single product rollout in Dell’s history – involves 14 new i486-based series systems.

Coleman says the new battleground will be on ‘the value front.’

è Christie Brown has reformulated its Chips Ahoy! cookies in an effort to compete with Loblaws’ highly successful President’s Choice brand – Decadent Chocolate Chip.

Launched in the late 1980s, Decadent Chocolate Chip has been steadily winning over consumers on the strength of its butter-rich formulation and its generous helping of chocolate chips.

Christie’s new entry, Chunks Ahoy!, is made of chunks of chocolate, rather than chips, and has 30% more chocolate content than in the company’s Chips Ahoy! brand.

Chips Ahoy! has been reformulated to contain 25% more chocolate chips.

And the Chips Ahoy! line has been extended to include Rainbow Chips Ahoy!, which contain candy-coated chocolate chips.

The national product roll-out is being supported by a multimedia marketing campaign, focussing on Chunks Ahoy!
