Opportunities abound, all of them nestled neatly around you. Your very own campus, for example. Take for example, the very recent startup www.UniGo.com, riding the wave of online user generated content and the owner's recognition of a the lack of useful information and copious amounts of bias information, as provided by the University, for incoming and prospective students.

UniGo.com, only covering universities in the states (but hey, maybe you can start reviewing your own University) is not a completely unique idea. www.uTours.ca, currently under construction, but was live not too long ago, was very similar. Comparatively speaking, the content of uTours is slightly less user generated, although there are some ranking services, but their business model is also slight different from UniGo.com.

uTours implemented a pretty diversified strategy that went beyond just the internet. The forged some alliances with big name companies in Canada because they offered value to students, a really lucrative market. Further, they had a variety of revenue streams in different places, notably a "uTours DVD" that contained lengthy videos about your favourite university.

I don't have their financials, so I can't comment on whether or not their products were successful. But there's always a lesson to be had: for any given business idea, there can be six or seven revenue streams. Don't limit yourself to any one in particular. In many cases, chances are you won't end up being dependent on the revenue stream you first came up with.

It's also worth noting that you don't want to diversify your efforts too much. If making DVDs and pursuing that distribution channel isn't performing or growing at the rate you need it to, it may have a negative effect on the rest of your business. There's a lot to be said about a niche (or specialization strategy); your efforts are focussed and your customers are happy.
