When I was assembling the ancillary B-Roll material for the latest Silicon Graffiti video, I wanted to do a segment that charted the growth of electronic media, from three national television networks in the 1950s, to several hundred at the turn of the century, and then compare that to exponentially more rapid growth of the Blogosphere, from a few million in 2004 to 112 million plus today, according to Technorati.

I had remembered a pretty cool Edward Tufte meets Spirograph chart of the Blogosphere from very shortly after we went online in March of 2002, and used a screen capture of it, which appears at about the 5:05 mark of the video, rotating 360 degrees via a little 3-D animation to add some kinetic energy to an otherwise still photo:

But to the best of my knowledge, the above chart hasn't been updated for several years. I wish I had known about a successor to that format a couple of weeks ago, as I would have surely incorporated it into that portion of the video. It's a somewhat similar map of the Blogosphere galaxy, though the emphasis appears to be on a few hundred of the top political sites. Which makes sense--the Blogosphere is so huge today, it must strain even Google and Technorati's capabilities to map it all.

I'm happy to say that we made the cut--here's our position in the political Blogosphere--center right, but not too far out into the whichy thickets, which makes sense:

And here's a close-up of that quadrant of the galaxy, and some of our neighbors orbiting nearby:
