Yahoo will begin supplying ads from its partners later this month, the company said Wednesday.
Yahoo already is the exclusive mobile-advertising partner for 3 UK competitor Vodafone.
Yahoo has signed up 3 UK, a mobile-phone network operator in the United Kingdom, to sell banner ads and sponsored links on the company’s Planet 3 portal site for mobile Internet use.
“We believe Yahoo has the experience to help us take full advantage of our advanced portal and unique all-3G subscriber base,” Neil Andrews, 3 UK’s head of on-portal advertising, said in a statement.
