Off-shoring has been adopted by banks and other financial organisations in the West since the 1980s, but it is only in recent years that it has become popular in other industry sectors as its financial benefits over more local outsourcing have become recognised. Evidence indicates that off-shore workers have a lower incidence of failure and cost less to employ than workers based locally.
