In January, Masterfoods USA, One of the World's Leading Food

In January, Masterfoods USA, one of the world's leading food manufacturers, announced its renewal of the FLW Outdoors sponsorship for the 2003 tournament season. The food company that owns such brands as Snickers, M&M`s, Uncle Ben's rice and Pedigree dog food has been a partner of the premier fishing-tournament organization in the United States since 2001. During the 2003 season, Masterfoods USA will promote its new Snickers Almond Bar to the nation's 55 million anglers. This will mark the company's second promotional campaign introducing a new product during FLW Tour events. During the 2001 season, the company promoted its Snickers Cruncher Bar, a crisped-rice version of the original. The partnership ensures visibility for Masterfoods USA along FLW Outdoors` broad spectrum of tournament circuits that includes the $5.76 million Wal-Mart FLW Tour, the world's most lucrative bass-tournament series; the $3.88 million EverStart Series, the pathway to the FLW Tour; and the $3.07 million Wal-Mart RCL Walleye Tour, the world's most lucrative walleye-tournament series.
