TalkSport has secured a six-figure deal with Xerox to sponsor the station's golf coverage.
As part of the deal, Xerox is sponsoring a promotion that asks listeners for their funniest office stories.
The deal was brokered by TalkSport's sales house Impact and Total Sponsorship.
Impact sponsorship executive Matt Wilson said: "This deal means Xerox will reach its target audience of business decision makers."
The deal comes a week after TalkSport's owner The Wireless Group reported ad revenues for the first four months of 2003 were flat against the same period in 2002.
TalkSport revenues were also unchanged at £11.2m and turnover rose by just more than one per cent.
TWG chief executive Kelvin MacKenzie said that "visibility had become even shorter" since the outbreak of war.
Revenues at TalkSport's sponsorship and promotion team were up by 35% for the first quarter of the year.
