Org charts haven't evolved dramatically over the last 20 years; it's usually pretty easy to find the person you are looking for or, when introduced to someone, to get a good sense of what they do from their title. As luck would have it, though, none of these rules seem to apply to streaming.
Over the last nine years, I've spoken with thousands of users across the enterprise, government and education sectors. And I can say with some level of certainty that no more than 5% of the people I've spoken with share the same title - despite the fact that they were all involved with streaming. To illustrate this point, here is a small sample of customer contact titles from deals we closed last month: Creative Media Manager, Internet Broadcast Engineer, Director Web Architecture, Director of Online Communications, Webcast Manager, Online Marketing Director, Online Event Services Manager, and Director of Online Training. And those were the intuitive ones, insofar as they indicate a technology or online media expertise.
 
I suspect part of this phenomenon can be attributed to the fact that streaming is a relatively new technology that, in many cases, gets squeezed into an existing group or thrust upon someone who, the day before, hadn't thought twice about it. But I think the real reason derives from streaming media, itself, and its diverse applications and requirements.  A streaming initiative can originate in so many different areas of an organization because, quite simply, it can be used productively for so many applications. In the old days (i.e. 2001), we saw streaming being used predominantly for corporate communications. Now, it's being deployed for everything from training to damage control to marketing to sales to internal town halls to partner relations. And those initiatives are just as often spearheaded by the subject matter experts (e.g. Director of Marketing) as they are by the technologists or services divisions that are essential to the process.

But I think there's more, because to be successful with streaming as an organization - regardless of what you're trying to accomplish - you need cooperation (or at least détente) among a host of different groups that range from the service provider to the subject matter expert to IT to the infrastructure folks. It's no wonder why the vendors and the business users are both trying to unravel all of the titles.

But please don't mistake this for grumbling. I love diversity and the fact that there are probably 500 people in each organization (all with different titles, of course) that are interested in streaming.  One might even want to talk to me.
