Blaine made street magic populare. The kids who saw the show wanted to do just that. Some magic shops even has a "street section".
I enjoy stage magic more then street magic.
In my opinion, Blaine took the magic from the stage, to the street. Or more importantly, to people that aren't expecting magic. That's where the best reactions come from.
The majority of people that get to see magic, are either watching it on a T.V. special, or pay money for tickets to a magic "show". Either way, they are expecting smoke and mirrors, camera tricks, and confederates. The most audience members that don't beleive in magic, the person randomly picked form the audience, was "randomly" picked from the audience. They still have this feeling in the back of their mind, "If I was there", or "If I was up closer to the stage".
Carnival magicians like Blaine, bring the magic up-close and personal. Where people have it in their mind, "I AM there", "I AM up close!", "That IS magic!".
