Street magic falls into two genres; traditional street performance and guerrilla magic.
Traditional street performance
The first definition of street magic refers to a traditional form of magic performance - that of busking. In this, the magician draws an audience from passers by and performs an entire act for them. In exchange, the magician seeks remuneration either by having a receptacle for tips available throughout the act or by "passing the hat" at the end of the performance.
Street magic most often consists of sleight of hand, card magic, and occasionally mentalism, though the ability to draw and hold an audience is frequently cited by practitioners as a skill of greater importance than the illusions themselves.
Anthropologists chronicle this form of street magic from approximately 3,000 years ago - and there are records of such performers across the continents, notably Europe, Asia/South Asia and the Middle East. While it is a very old performing style, its history is not particularly well documented in print. In his diary, Samuel Pepys mentions seeing magicians performing in this fashion and one can see street magicians in depictions by Hieronymous Bosch, William Hogarth, and Pieter Brueghel. Book XIII of Reginald Scot's Discoverie of Witchcraft (1584) describes magic tricks of the type performed by buskers in the 16th century.
New York based artist and magician Jeff Sheridan is regarded as one of the pre-eminent U.S. street magicians to emerge from the surge in street performance artistry which began in the late '60s. He authored the 1977 book, Street Magic and allegedly was one of the performers who inspired and taught the young David Blaine after Blaine saw Sheridan perform in Central Park.
More recently, other performers have garnered accolades from the magic community for their contributions to the art. Jim Cellini (aka Richard Sullivan) has been a full-time street performer since the 1970s and has published a book (Cellini: The Royal Touch) and DVDs (The Art of Street Performing, volumes 1 - 3) on the subject. Gazzo Macee (aka Gary Osborne) has been a full-time street performer since the 1980s and has published a booklet ("The Art of Krowd Keeping" written for Gazzo by Danny Hustle and Jim Wells) and DVD (Street Cups) on the subject. David Groves has been a part-time street performer since the 1990s and has published a book on the subject (Be a Street Magician: A How-To Guide). Cyril Takayama has produced and starred in three TV shows on street magic and produced one street-magic DVD.
The second category is more appropriately called "guerrilla magic" It is a relatively recent style of performing magic illusions where the magician performs a single trick or two in a public space (such as on a sidewalk) for an unpaying audience. The desired effect of this "hit and run" style of magic is to give the audience a feeling that what they are seeing is impromptu, unrehearsed, and experimental.
This style of "street magic" is associated with David Blaine (who popularized the term) and more recently, Criss Angel, Derren Brown and Cyril Takayama. The format was developed to play well on television beginning with the 1997 ABC television special David Blaine: Street Magic. Many magicians respect Blaine's choice of material and give him credit for creating an image of the contemporary magician distinct from other magicians in recent television history, such as David Copperfield or Doug Henning. However, magic historians, such as Jamy Ian Swiss note that "guerrilla magic" is primarily associated with only a few individuals who perform on television and certain magic dealers that sell effects to amateur magicians who watch these programs. Eugene Burger opined to Jamy Ian Swiss "On one level it's the ultimate trivialization of magic: accosting strangers on the street."
