Lucozade Energy is the sponsor of the 2009 Big Brother TV series. According to brand owner GlaxoSmithKline (GSK), the sponsorship, supported by a £12m marketing campaign, is expected to drive significant sales for the brand around the series finale later this month.

The brand has a presence across all the main shows on Channel 4 as well as E4 spin-off shows Big Brother’s Big Mouth and Big Brother’s Little Brother.

To help retailers make the most of the sales boost from the series finale, GSK is giving retailers the chance to win £50-worth of Lucozade Energy.

There are five prizes.
