Soft drinks company AG Barr has extended its sponsorship of The Scottish Football League for a further three years.
The new Irn-Bru deal, which will start in season 2010/11, is worth more than £3m to the SFL. The company began its sponsorship of Divisions One, Two and Three in 2007 after the leagues were left without a sponsor in season 2006/07.
The SFL and the makers of Irn-Bru say they plan to build on the investment they have made at grassroots level.
SFL chief executive David Longmuir said: "I look forward to continuing our hard work with Irn-Bru and to more exciting and innovative campaigns ahead."
He and Barr's head of marketing Adrian Troy promise fans several new initiatives over the next three years in which they can get involved with their local club.
"We hope that we have been able to make a significant contribution to the league," said Troy.
