In the next 10-24 months, several changes in the tech landscape will create a dramatic shift in web, making video a more and more important content form.

First, cloud storage will become more and more popular. Today, enterprise-grade services from companies like Amazon and Google are vying for market dominance in this field.

Also already in the works, major phone carriers are fighting to win the "4G" race. While some 4G networks are in place now, soon mobile internet speeds 4x what they are today will become much more widespread.

Add to that picture the rapid evolution of devices. All major players in consumer computing have announced their "slate" computers to compete with the iPad. And while 30% of today's U.S. mobile phones are smartphones, Nielsen projects that share will be 50% by the end of the year.

Finally, consider one last development: the growing number of context-aware websites and apps, following Amazon's "You might like..." model. More and more, content will be dynamically assembled, pulling from other sources, like Facebook, TripAdvisor, websites with RSS feeds, databases like NAVTEQ and more.

The success of those assemblies with audiences will depend on specificity, so just as in SEO, a long-tail approach can build bulk audience in micro-units. Your content may not be picked up for "beach" but may rise to the top for "best tide pools in Florida."

Together, these developments spell two important near-term changes in media: web/mobile will become the ruling channel, and video will become a much more dominant media form, displacing static text and images online.

This doesn't mean text and images will go away, but video will be first choice for many audiences, and for all will be as familiar and accessible online as text and images are now.

Competing in this landscape will mean delivering information in that form, and DMOs should begin planning how they'll provide content on meetings, attractions, restaurants, transportation and more in video: tightly focused topical pieces that work as well on your site as they do in a dynamic, context-aware content environment.
