Bridgestone and Microsoft have been granted exclusive contracts to be the sole suppliers, of tires and ECUs respectively, of Formula 1 beginning in 2008.
The announcement was made following this Wednesday's meeting of the FIA World Motor Sport Council in Paris.
The move to a single tire supplier and standardized ECUs (Electronic Control Units, responsible for a car's engine management) is part of the FIA's radical cost-saving package announced earlier this year for introduction in '08. Both Bridgestone and Microsoft will supply F1 through 2010.
