The MIT blackjack teams have taken millions of dollars from casinos around the world by training students to play blackjack scientifically. ABC News has covered them, the History Channel made a special on them, bestselling books have been written about them, and Hollywood has made the movie "21" with Kevin Spacey about them. Semyon Dukach created Blackjack Science in order to share his blackjack secrets with the world. At this time Semyon is no longer offering Blackjack Seminars or selling DVDs, because he is focused on running smtp.com, which provides bulk email marketing and transactional email delivery to legitimate senders. SMTP.com also manages the reputation of smtp servers and processes any possible abuse reports from receiving ISPs.
