The Big Mo

The Big Mo ("Big Momentum") is behavioral momentum that operates on a large scale. The concept originally applied to sporting events in the 1960s in the United States, as momentum appeared to have an effect on a team's performance. Successful teams were said to have "The Big Mo" on their side. This has since extended situations in which momentum is a driving factor, such as during political campaigns, social upheavals, economic cycles, and financial bubbles.
