Indian was really the pioneer of the offshore call centre industry. At the end of the 20th century, companies in The UK and USA started to move call centres away from their home countries to India. At first, the call centres were located in the major cities such as Delhi, Mumbai, Chennai & Bangalore but gradually started to move to smaller towns as costs escalated as did attrition rates.
In the period 2003-2005, call centres in India became far less popular due to poor public perceptions. Many of these call centres were relocated to other countries with The Philippines being the primary beneficiary. Some call centres were also repatriated but with limited success. India remains a popular destination with non-voice BPO work but its popularity for call centre work has dwindled. Many of the larger Indian owned company have invested heavily outside of the country including in The Philippines, Latin America, The United States & The United Kingdom.
