The two companies will share broadcast, online and interactive sponsorship of the tournament, which runs from 9 June for a month, as well as branding on ITV's promotional activity.
For Budweiser, the deal is part of a major marketing campaign highlighting its status as the official beer of the World Cup. As part of its deal with FIFA, the Anheuser-Busch brand will be the only beer able to feature the official World Cup logo on its packaging.
The lager will begin its push with a TV ad campaign that will use the 'You do the football, We'll do the beer' strapline that features on its FA Premier League ads.
The TV campaign will be supported by press advertising featuring the 'Genuine article' strapline, as well as a significant on- and off-trade push with a competition to win tickets to the finals.
The competition will feature on more than 100m cans and bottles in the UK. To win prizes, drinkers will have to SMS mobile phone pictures of themselves with a Budweiser bottle, each of which will have a unique number corresponding to a prize.
Budweiser's UK marketing director, Jim Gorczyca, said the deal marked the brand's biggest marketing campaign to date.
'Budweiser has been the official beer of the FIFA World Cup since 1986 and we are always looking for innovative ways to connect with adult audiences to promote our sponsorship,' he added.
ITV Sales brand partnerships director Gary Knight claimed there had been unprecedented demand for the World Cup package.
