Bestselling author Tim Ferriss took an unorthodox route this month, using the file-sharing site BitTorrent to promote his new book. For the last seven days, BitTorrent members had exclusive access to excerpts, unpublished writing and multimedia materials related to The 4-Hour Chef.

Today, BitTorrent revealed some statistics: “The Tim Ferriss 4-Hour Chef Bundle has now been downloaded 211,000 times. From BitTorrent, 85,000 visitors clicked to check out the book in the Amazon store, a huge number for the category. The audience has been highly engaged as well: 13% of visitors to the featured content page on BitTorrent clicked out of the site to watch the YouTube trailer, contributing to 1.4MM views16% clicked to the 4-Hour Chef site.”

In 2010, Ferriss hit the Amazon bestseller list with The 4-Hour Body, a book traditionally published through Crown Archetype. A number of bookstores have said they will not stock his new book since it is published by Amazon.
