You won’t find a more experienced tech b-to-b video producer than Fritz Nelson. Luckily for PR, he’s quite responsive and wants to open his door for virtually any worthy tech vendor.

They also can demo their software products using TechWeb’s Reviewcam tools. A new live San Francisco-based TechWeb show called “Valley View” has been soft-launched and will be rolled out full-force in 2010. And Fritz Nelson will be at the center of it all.
