Video's value isn't limited to educating customers about consumer products, though. It's equally useful for professionals, as I learned first hand myself earlier this year, when I was involved in making a decision about a pacemaker for a family member. Because I didn't know much about pacemakers, naturally, I turned to the Internet. I saw lots of complicated diagrams as well as brief articles about the procedure but what I found most useful were a series of videos by a doctor, describing how a pacemaker is installed as well as the risks of surgery.
Many lawyers already have videos posted on YouTube, but many of these videos are what I would consider "vanity pieces," telling about the lawyer rather than providing useful information. So even though video has been around for a while, there's still a wide open field for lawyers willing to create informative videos to help potential clients understand the issues involved in their legal matter.
