Name the single most influential event in the history of the NHL. Some would say collapse of the PCHA in the 1920s, or the television revolution that started in the 1950s, or the Soviet style play in the 1970s, or maybe even the lockout of 2004-05. All would be great choices, but one must also seriously consider the NHL's doubling in size from six teams to 12 teams - the 1967 expansion. Hockey's Original Six welcomed the Philadelphia Flyers, Pittsburgh Penguins, St. Louis Blues, Minnesota North Stars, Los Angeles Kings and the Oakland/California (Golden) Seals The Great Expansion: The Ultimate Risk That Changed the NHL Forever is a fantastic and in depth look at every aspect of the bold move - from the preparation and logistics to the team selection and player draft to the long term impact. At nearly 250 very well researched pages, this is easily the most expansive text ever on this subject. Buy The Book: Amazon.ca - Chapters - Amazon.com - Kindle Editio
