Amateur professionalism or
professional amateurism (shortened to
pro-am) is a
socioeconomic blurring of the distinction between professional and amateur within any endeavour or attainable skill that could be labelled professional in fields such as writing, computer programming, music or film. The idea was used by
Demos, a
British think tank, in the 2004 book
The Pro-Am Revolution co-authored by writer
Charles Leadbeater. Leadbeater has evangelized the idea (in "amateur professional" order this time) by presenting it at
TEDGlobal 2005. The idea is distinct from the sports term "pro–am" (professional–amateur), though derived from it.
