The first example is Minyannville Publishing & Multimedia which provides small animated clips of business and other headline news to major sites like Yahoo Finance, MSN Money, AOL Money, and Fox Business News. The main reason is their ability to offer fresh content that brings something new and different to these big sites so that their readership remains loyal. Independent content providers have a growing amount of leverage and opportunity to let their creative talents shine in front of many with those that focus on niches becoming hot commodities. More information for those that get the WSJ via an article entitled "Portals Think Small For The Latest News: Niche Sites Offer Access To Content As Gateways Battle Traffic Slippage."
The second, is from another newspaper article, this time from the Union-Tribune with an article entitled "Background-music provider puts shoppers in the mood." What I liked about this article was that PlayNetwork leveraged the basics of what they know with audio as a purchasing tool into a bigger business that also enables their customers to tie into new media outlets like web video, podcasts, and other multimedia services.
