One of the first recorded and well studied fads of the market were tulips in Holland, circa 1637.
Most adults today better know about a distant relative of Tulip Mania which occurred in the 1960s, Beatles Mania.
Little and big manias are continuing today. Recently, owl prints became quite popular. A few years ago, the real estate bubble exploded, ending a housing mania.
It appears my blog has been affected by hedgehog mania.
Hedgehog mania just burst though, it looks this this viscous hedgehog popped the bubble with his sharp, pointy teeth.
