Coca-Cola is gearing up for summer with a £3.9m marketing push focusing on music and happiness.

The activity, which kicks off next month, forms part of the brand's £80m 'The Coke Side of Life' summer campaign across its key brands. It will be led by the 'Happiness Factory' TV ad, which features the 'magical world' where Coca-Cola bottles are delivered.

The TV push also includes a new 10-second music-specific advert.

In an on-pack promotion, consumers will be given the chance to win more than one million iPods and iTunes songs. Prizes will be given away every minute of the day for eight weeks and will feature on two-litre, 500ml and multi-packs.

"Summer provides retailers with the biggest sales opportunity within the soft drinks category," said Anita Huntley, head of carbonates. "The 'Happiness Factory' is Coca-Cola's strongest UK TV ad to date and we are confident this promotion will be a success with all consumers, especially music-lovers."
