Editing Customer Relationship Management (CRM) (section)

===Historical Background===
The concept of customer relationship management started in the early 1970s when customer satisfaction was evaluated using annual surveys or by front-line asking. At that time, businesses had to rely on standalone mainframe systems to automate sales, but the extent of technology allowed them to categorize customers in spreadsheets and lists.

With the advent of advanced technology and the proliferation of customer data, companies started adopting the CRM approach, and by the early 2000s, it had become an integral part of business strategy.
