The constant proliferation of social networks, also called social media platforms, leaded to the fact, that nowadays even enterprises use this new way of engagement with their customers. Hence, the commercial use of social media in customer relationship management (CRM) is still in its infancy, this thesis aims at elaborating concrete B2C use cases for social media in CRM. When talking about the dialogue with the customers, it is impossible not to mention the CRM philosophy. As one of the major components for customer-oriented enterprises, its origin, definition, goals and areas of application can be found in this thesis too. The computer-aided acquisition of long-term profitable customers, up- and cross-selling to existing customers, rise in customer loyalty and incentives to repurchase, and the recovery of lost customers, enable enterprises to assert themselves in the market. Nevertheless, a radical change is arising in the traditional CRM market. Social media are subject to low censorship and enable end customers to actively participate and state their opinion. In this way, enterprises, which use solely traditional CRM, loose control of the communication step by step and have to adapt more and more to the customers' needs. By participating actively in social networks, vendors can recover parts of this lost control and by integrating social media with CRM systems gain control of communication, at least partially. This thesis shows the necessity of embracing the social media channel and elaborates concrete use cases for the business pillars sales, customer service and marketing. An analysis of existing social media monitoring solutions and the integration with market-leading CRM systems offers a practical orientation and shows the realization of the theoretical use cases in nowadays available social CRM systems. By starting with the root cause for the ongoing loss of companies' communication control, showing possible use cases, how to prevent its proliferation, and the practical realization of those use cases, the high value each enterprise, which is confronted with serious competition, should attribute to social CRM is emphasized.
