You can call them vlogs if you want. Videoblogging sounds better. If I even do one I might come up with a better name for one of those.
Anyway there is a blog where you can keep up with news about videoblogging called the Vlog Press Kit. A collection of stories and links with regards to the vloggosphere. The authors there hope to be able to help journalist learn a little more about videoblogging.
BTW, I haven't followed this scene too often because since "discovering" it in 2005 when I first started blogging, the scene has slowed down considerably. Kind of unfortunate but I suppose when it comes to one-man (or one-lady or one-person) it's basically very easy to do. That's not to say they don't produce.
Here's a videoblog I saw today and maybe you have some space at home to build a personal museum of stuff. This segment is courtesy of Lo-Fi St. Louis.
Also Videoblogging week is coming up next week during between the 1st and 7th of April. Have your broadband internet connections ready!!!!
