Apple, Inc. (AAPL) only entered the mobile advertising market a few months ago, but the company has already been successful at taking away crucial mobile advertising revenue from giants such as Yahoo! Inc. (YHOO) and Google, Inc. (GOOG).

Apple was definitely a late comer to the mobile advertising party, but it has nonetheless made a quick impact. According to a report from Bloomberg Businessweek today, Apple could end the year with a nice 21% share of the market.

Twenty-six percent of businesses using Twitter say they'd pay for the right services, and that might just be good enough.

WebBizIdeas.com polled 850 Twitter business users about what services would lead them to pry open their wallets. Three quarters of them said they either weren't crazy or were unsure about paying for additional features like analytics (31% and 43%, respectively), which sounds like a menacing amount. Yet, the size of this social media environment may make the 26% sufficient.

Modest goals don't seem to be on the agenda for Facebook. Sheryl Sandberg, the company's chief operating officer, is shooting for Google (NASDAQ: GOOG). The social networking company seeks its ad market as rivaling (or even surpassing) Google's search ad market in size. Facebook says it's on target to bring in $500 million in revenue this year (Sandberg didn't confirm it, though).

With its 300 million users, Sandberg has been trying to convince the world that her company has a solid business model in place. The perception that eyeballs don't necessarily equal dollars, born of the internet boom a decade ago, isn't necessarily true any more, as demonstrated by Google's ability to monetize search (and hit record profits) has demonstrated. For the third quarter of 2009, the search engine giant raked in net revenue of $4.38 billion.
