Tim Ferriss, author of the bestselling book, The 4-Hour Workweek, has just posted this on his blog. Its three tips on how to give a good elevator pitch. Being able to pitch a TV show in under a minute is a useful skill in the entertainment industry (or any industry for that matter) and should be practiced. There isn't much instruction on the blog, but his tips are a really good starting point.
The first video is Mr. Ferriss giving his elevator pitch. The second is only useful if you speak German.
