The extensive user base that Apple (NASDAQ:AAPL) has established over the years has the potential to create at least three new sources of revenue for the technology leader. First, as Apple develops its near-field communication capabilities, mobile payments may become more viable. Second, with the release of iTunes Radio, Apple may be able to compete with Pandora (NYSE: P) and garner more users. Finally, if Apple is able to successfully introduce new advertising capabilities, it may be able to push into Google's (NASDAQ:GOOGL) turf in mobile ads.
In the following video, Fool.com contributor Doug Ehrman discusses these developments and how iTunes may allow Apple to break into new markets.
