Across the Quattro network of premier mobile web sites, the comScore/Quattro Survey found a significant percentage of the audience to be “mobile only” visitors to these brand destinations. This unduplicated mobile audience uses the web daily and visits these sites in particular. The key statistics concluded:

36% of respondents indicated that they do not access the companion wired web site of the publishers they visit on the mobile web
46% of the respondents are daily visitors to Quattro Network premier mobile web sites
Furthermore, Quattro’s own Network efficiency study revealed that brand marketers realized an average 2% CTR on targeted campaigns with visitors to advertiser micro-sites averaging 3 page views per visit. The combined results clearly demonstrate that the Quattro Network mobile audience is unique and engaged and that brand marketers are driving ROI through targeted mobile campaigns.

“The survey showcases the viability of the mobile Internet as a strong platform for premium content and premier brands to reach a highly interactive, unique audience – anytime, anywhere,” said Andrew Miller, CEO of Quattro Wireless. “Mobile is measurable media. The Quattro Network is a quality network full of category-leading Publishers with a proven track record of driving ROI for advertisers. The combination of the two gives marketers a strong, cost-effective platform to turn to in these challenging economic times.”

“Consumers are becoming increasingly reliant on their mobile devices for news and information,” said Mark Donovan, senior analyst of comScore Mobile. “This M:Audit study with Quattro confirms the industry’s notion that relative to online, the composition of the mobile web audience is unique and in some cases unduplicated. In all cases, this audience is highly engaged with the medium.”

Quattro Wireless and comScore conducted this survey during seven consecutive weeks in August and September 2008.

The advanced device market has seen enormous growth in the past year, with multiple reports projecting 2008 sales to increase more than 50% over last year. Consumers have loudly declared a broad acceptance of these once-thought business-only devices, and the advertising industry has taken notice.

These devices, which include iPhone, BlackBerry® and Windows Mobile® handsets, represent the fastest-growing segment of the over three billion monthly impressions that comprise Millennial Media’s mobile advertising networks (August 2008). Millennial Media’s advanced-device network, which includes a subset of over 120 million monthly iPhone impressions, provides advertisers with access to the largest possible audience of iPhone and advanced device consumers. Millennial Media’s networks in total reach over 50% of the U.S. mobile Web audience.

“Mobile users from ‘tweens to busy moms to tech-savvy men have discovered the value of staying connected to the Web while mobile, and advanced devices such as the BlackBerry, iPhone and Windows Mobile handsets are delivering this growth,” said Paul Palmieri, president and CEO of Millennial Media. “As a result, smart publishers are leveraging smart phones to win new audiences, and are using mobile advertising to create new revenue streams. Advanced devices have become mainstream.”

In continuing its trend of defining the industry, Millennial Media is addressing the strong consumer adoption and commensurate attention from advertisers and brands with the launch of a suite of custom advanced device solutions. As advertisers seek to extend their campaign reach beyond the wired Web, Millennial Media today introduces new ad units which leverage advanced devices and high-speed networks. Newly launched ad units include JavaScript™ creatives on iPhone, vector-graphic creatives on BlackBerry and Flash®-based creatives on Windows Mobile devices, as well as additions to the company’s suite of engaging post-click solutions.

And, whether it is a mobile website or iPhone application, Millennial Media has a revenue solution for publishers.

With BlackBerry dominating the advanced-device market, Millennial Media is continuing to expand its suite of rich, engaging mobile creatives, custom sites, landing pages and post-click solutions for the entire family of BlackBerry devices. These solutions include custom mobile sites, developed and hosted by Millennial Media, and leveraging vector-based graphics to achieve rich-media effects designed specifically to maximize brand impact. Additionally, in anticipation of Research In Motion’s v.4.6 launch, Millennial Media has refined its entire suite of post-click solutions to support this updated development environment and browser.

Millennial Media has developed and delivered new mobile Flash creatives and ad support capabilities through its partnership with Mobopia and its Xuinet service.

Android™

In anticipation of Android-based devices coming to market in Q4, Millennial Media has developed ad units based on CSS3 that match the compelling features of current iPhone creatives.
