High-end mobile phones, like iPhone, Android-powered devices and the Palm Pre , continue to grow — Gartner estimates that global sales of smartphones will soar by 27% in 2009, to 177 million units. Naturally, as a result more and more people are browsing the web on the go.

Because these devices offer a browsing experience that is similar to desktop computers, advertising on smartphones is a natural extension for any AdWords campaign. However, it's not always been easy for advertisers to reach people on smartphones. That's why we're investing in new high-end mobile advertising products such as our search ad options for high-end phones and AdSense for mobile applications. We hope to make advertising on high-end mobile devices as intuitive, effective and user-friendly as our existing AdWords tools.

Today, we're excited to announce a new feature for our AdSense mobile publishers that enables them to serve text and image ads on their sites — specifically on these high-end smartphones. This helps mobile publishers earn revenue and fund more mobile-specific sites and web content.

New features like this help to nurture the smartphone ecosystem by encouraging the creation of more mobile content and by helping advertisers to grow their businesses by reaching new audiences. Our users' experience is also improved, with increasingly relevant and device-optimized mobile ads that load faster and fit better on small screens.
