OutdoorArtsUK began in the late 1990s as ISAN (The Independent Street Arts Network) when a group of programmers and producers began to meet, network, pool resources and lobby for greater investment in Outdoor Arts, particularly from Arts Council England and local authorities.
In 2001, ISAN was formally constituted as an organisation and, through the support of project-based funding from Arts Council England, appointed part-time and freelance workers for the first time to further develop its role and function.
