Scroeder's book and the first video debuted Monday.
A new video will be posted each week until Nov. 18 on www.youtube.com/thesnowballbook.
Amazon.com ranked the Buffett book first on its best-seller list Tuesday afternoon.
Schroeder's book has been eagerly anticipated because it is the first one Buffett has cooperated with. The book delves deep into Buffett's personal life as well as his business record to show what's behind his ideas.
Buffett is chairman and CEO of Berkshire Hathaway Inc.
