[1] Even after oscillating between the realms of legality and illegality, street vending in Mexico and even in other parts of the world, is not the exception but rather has been a norm when it comes to commercial activities.
In New Spain, outside of the controlled mercado or market on the Zócalo and other squares, street vendors emerged, then called buhoneros.
[6] In 1993, the first of several major efforts (each only partially successful) to reduce street vending in the Historic Center of Mexico City began, with the removal of about 10,000 vendors from the streets and construction of markets (plazas comerciales) to re-accommodate them, as well as subject them to tax codes, health regulations and otherwise pay the full "costs of formality.
During the 1990s and 2000s street vendors have paid union leaders "dues" in exchange for the right to occupy a piece of sidewalk without city permission, an illegal act.
[8] Finally, in October 2007 the streets of the Historic Center were cleared of vendors with much success, which was considered a victory for mayor Marcelo Ebrard.
