Best Buy is now running mobile advertising within the brand new msnbc.com application for the iPhone and iPod touch.

The advertising encourages app users to click to get the deal of the day or be linked to Best Buy's Twitter feed. The application provides a sturdy platform for Best Buy's ads as msnbc.com was named the No. 1 news site by Neilsen Online and the application offers the same exact content from the site.

"The Zumobi Network sees this as less of a challenge and more of an opportunity to give partners such as msnbc.com an enhanced opportunity to offer their content to the iPhone and iPod touch audience," said Cindy Spodek Dickey, vice president of Marketing at Zumobi, Seattle, WA.

"Mobile apps, and in particular the Apple App Store, are becoming a mainstream part of the mobile marketing culture, making them a "must have" for companies that are seeking to reach their audience throughout the day," she said.

"Media brands in particular are looking to reinforce their positioning, increase their audience, and ultimately generate new revenue streams from these initiatives."

Zumobi has integrated a Best Buy sponsorship into the application which links to the Best Buy featured deal of the day and incorporates Best Buy's Twitter feed.

The flagship advertiser for the application is Best Buy, a consumer electronics and technology retailer.

With Best Buy, msnbc.com hopes to prove that the msnbc.com application is a worthy environment for advertisers because of its increasing audience and the flexibility of the iPhone platform.

The new msnbc.com application lets users access to breaking news, videos and photos straight from msnbc.com.

The application features a dial that users can tap to access the news topics that best fit their interests along with NBC News, MSNBC cable shows, blogs and Twitter streams straight from their mobile phones.

Msnbc.com claims that the expansion of its mobile platform was intended to reach the millions of tech savvy news lovers with everything that the Web site has to offer, direct via the user's iPhone or iPod touch.

Msnbc.com also boasts to provide a rich environment for premium brand sponsorship that goes way beyond banner ads for advertisers that would like to work in the mobile space.

The msnbc.com application allows users to immerse themselves in the news that travels as fast as we do these days, without ever having to slow down from an on-the-go lifestyle.

The application features a radial interface which offers easy navigation for users to see all of their options clearly on the home screen.

User settings make it possible to scan and scroll through content, play and pause video, choose and read news stories, and tweet articles or follow tweets from NBC News and MSNBC cable anchors.

"The Zumobi Network is confident mobile apps will continue to be ubiquitous as the trend for reliance on the Third Screen increases," Ms. Dickey said. "We believe that this trend will grow because people are consuming huge amounts of content, social media and other ways of expression on a daily basis.

"These behaviors create an incredible opportunity for mobile advertisers to not only reach end-users, but to target their ads better and see a direct ROI as a result," she said. "The mobile advertising sector is just getting started and will become a standard piece of any comprehensive marketing plan for brands globally."
