Out of the hundreds of articles and posts out there on how companies should utilize social media and Web 2.0, CNN seems to be one of the few major corporations out there that have paid attention. CNN is one of the few broadcast networks with an expansive line of shining examples in the Web 2.0 space, from basic RSS and bookmarking options to embeddable videos, and its fully user generated content platform iReport.com.

What amazes me most about CNN has not been the millions of iReport submissions or the Web 2.0/social media, it's that it seems CNN is now the first official broadcast network (not just news related) to start using Twitter and heavily promoting it on air. For instance, today I watched as CNN Anchor and Editor Don Lemon fished for Twitter replies after various segments. I’m sure this is only one of the many mentions to come and I'm sure we’ll see a large jump in his followers from here on out.

So, CNN gets it… What do you think about their on air Twitter plugs? Is there any other major company you can think of that’s an early adopter and getting it right?
