We have come a very long way since lawyers first embraced direct mail marketing. Websites are almost ubiquitous (or at least the absence of a website probably sends the message that a law firm is behind the times.) E-mail marketing is now being widely used by major law firms to supplement (or in some cases to replace) U.S. mail and blogs like this are becoming increasingly common.
It seems that podcasts may be the next wave. It is very logical that lawyers should turn to this medium. While lawyers are supposed to be masters of the written word, increasingly, we live in a multimedia culture where busy professionals do not have the time to read. Podcasts provide a very inexpensive way to basically create a private radio broadcast (in the same way that a blog creates a private newspaper.)
