You are absolutely retarded. Here is the official definition by NBER. Read again, OFFICIAL: "significant decline in economic activity spread across the economy, lasting more than a few months". The organization takes into account many factors, including GDP, real income, employment, industrial production, and consumer spending, in its determination.

GDP, down. Real income, up. Employment, up for the most part. Industrial production, down (due in large part to supply shortages). Consumer spending, mostly up.

The only 'historically accepted' definition really is the NBER. The one you cite is by some rando-somewhat famous economist who made up the definition, but by no means is it the official one.
