PepsiCo has extended its sponsorship of the National Football League (NFL). The deal, originally due to expire after the 2006 season, has now been extended by an extra five years.

The new agreement, worth just under US$500m, will enable the group to use NFL trademarks on its Pepsi, Tropicana and Frito-Lay brands through until 2011.

The world's second-largest soft drinks maker is planning to buy advertising time on the NFL Network, as well as increasing its spending on commercials during NFL game telecasts. The new deal comes after efforts to revitalise the company's trademark Pepsi soft drink, including song giveaways on Apple's iTunes.

PepsiCo's Gatorade unit, the biggest-selling sports drink, also signed a similar extension with the league in February.
