Flash Mobs Go Corporate (At Least It's More Paid Work For Dancers)
"The original flash mobs often had little obvious purpose and were decidedly noncommercial gatherings by amateurs, says Bill Wasik, who is widely credited with creating the first flash mob, in 2003." No more. "Dance Mob Nation, based in Los Angeles, says it charges an average of $2,000 to $4,000 per event and as much as $10,000, depending on the presentation."
