Myspace recently reinvented itself as an entertainment-sharing site, with a new Facebook Mashup feature to boot. Its developing relationship with Facebook was partially aimed at making the site more appealing to marketers, and Myspace may have even more ad pull now that it has announced mobile updates just as mobile ads are predicted to skyrocket.

While reports indicate that News Corp is considering selling Myspace, the company announced a new mobile website and iPhone app that could bring new advertising life to the site. The new features aim to "meet [consumers'] desire to consume entertainment news and content anytime, anywhere and from any device," officials say.

Marketers with a presence on the space may appreciate its enhancements for on-the-go discovery, including breaking music industry news, expanded mobile video content and celebrity information. Plus, the updates allow consumers to more easily share what they find on Myspace across social networks via their mobile devices, potentially maximizing brands' exposure.

These developments mean entertainment-related brands that step up their content marketing strategies on the site stand to gain more traffic from mobile owners. At the same time, brands across industries might also take notice of this Myspace development because it aligns the social channel with a rising platform – mobile advertising.

According to a BIA/Kelsey, mobile ad revenue will reach $2.03 billion by 2014, demonstrating a 69 percent increase over 2009. Mobile search ad revenue is expected to drive growth, increasing 93 percent from $59 million in 2009 to $1.6 billion in 2014.
