Back in 2000 or 2001, I made this "advertisement" for LeatherZ. At the time, I don't even think Youtube existed. I had the idea that customers would be more likely to buy products from us if they came with videos that showed how to install them. So I shot videos of myself installing everything we sell and narrating the instructions with voice over. We used to give away CD-ROMs (yeah, not DVD, not memory stick) with all the installation instructions on them. This video was meant just to be fun and make the company look good. I still like it, years later.
This second ad was for the "Technical Installation Disc" mentioned above and it's fun too.
