Marketing in its present form has come a long way and is evolving day by day. However, there is a huge history associated with marketing as it has evolved through multiple eras which are as below: -

• The Production Era
• The Sales Era
• The Marketing Department Era
• The Marketing Company Era

According to my knowledge the marketing has evolved over five eras namely the production era, the product era, the selling era, the marketing era, and the holistic era.

The marketing has deep roots in the history as it has been in trend since the business started even in local markets. Effective marketing is beneficial for economic growth as it brings more customers and also it benefits the customer by taking them to the source which can fulfil their demands. Hence, the eras from which the marketing has emerged out are:

• The Simple Trade Era
• The Production Era
• The Sales Era
• The Marketing Department Era
• The Marketing Company Era
• The Relationship Marketing Era
• The Collaboration Era 

There are total 7 eras of marketing which include: simple trade era, production era, sales era, marketing department era, marketing company era, relationship marketing era, and collaboration era.

The marketing department era, the sales era, the production era, and the simple trade era are the four eras of marketing.
