The wireless services industry faces unique challenges when including ads in Internet content delivered on handheld devices, such as smaller screen sizes and lower data-delivery speeds. OmniSky and DoubleClick are working with wireless users to develop and test innovative and compelling advertising solutions that remain consistent with the rich user experience of the OmniSky service and are relevant and valuable to users. In addition, the two companies are working as board members of the Wireless Advertising Association to develop creative, delivery and measurement standards that benefit the entire wireless industry.
