Be fair: the link references the standard, but does so in order to say that that's not how the NBER defines a recession.
> The NBER uses a broader definition of a recession than commonly appears in the media. A definition of a recession commonly used in the media is two consecutive quarters of a shrinking gross domestic product (GDP). In contrast, the NBER defines a recession as "a significant decline in economic activity spread across the economy, lasting more than a few months, normally visible in real GDP, real income, employment, industrial production, and wholesale-retail sales". Business cycle dates are determined by the NBER dating committee. Typically, these dates correspond to peaks and troughs in real GDP, although not always so.

> Though not listed by the NBER, another factor in favor of this alternate definition is that a long term economic contraction may not always have two consecutive quarters of negative growth, as was the case in the recession following the bursting of the dot-com bubble.
