Yahoo-Google agree online ad deal
Yahoo has agreed a deal with Google which will see Yahoo use the search engine giant's advertising technology.
Under the agreement, Google ads will appear alongside some Yahoo search results in the US and Canada.
The announcement came after Yahoo said it had failed to persuade Microsoft to renew its bid to buy all of the internet company.
Recent talks concluded after Yahoo rejected a Microsoft proposal to buy just its online search business.
Yahoo said the agreement with Google could be worth up to $800m (£410m) in additional revenue every year.
