The term
The term Velvet Revolution was coined by a journalist after the first events and it caught on in world media and eventually in Czechoslovakia. The media, riding on an infotainment wave, saw this success and started the tradition of inventing and assigning a poetic name to similar events – see color revolution.
It is believed that the term originated from the various communist opposition groups which met in theaters such as the Laterna Magika, velvet referring to the velvet ropes found in all these theaters.[citation needed]
