Tesco is using the simplistic style and humour of its current advertising campaign in an attempt to repeat the successful sales performance it saw last Christmas. The new ads, by Lowe London, use Tesco's now distinctive style and feature products on sale in its stores with amusing narratives by celebrity voiceovers. One spot promotes Tesco's ultra slim Christmas Tree. The voiceover, by Frank Skinner, says: "Yes its elegant, it's trendy and it's space efficient. But best of all it makes your presents look bigger." Last year, Tesco reported that sales grew 7.6% in the seven weeks to Christmas. The supermarket is the UK's biggest with £1 of every £8 spent in its stores.
