Public relations are a holistic discipline that encompasses various management processes and a wide variety of tasks concerning analyzing business surroundings and stakeholder communications. Public opinion has always been fundamental in public relations and, in the context of impacting public opinion, PR has been present in society since the beginning of written history. Technologies that influence communication processes in society also influence changes in public relations, an example being the invention of the printing press and later the sciences of psychology and sociology. Marketing is an area closely tied with public relations and the base concerns marketing focuses on are products and services. The dividing line of the areas of responsibility of marketing and PR can be blurry, considering both functions direct communications to often the same stakeholders. There are cases where marketing and PR tasks and responsibilities overlap, like with Starbucks where the product isn't solely coffee, but the complete experience of going to Starbucks, and therefore the reputation management that would traditionally be the responsibility of public relations becomes the same as the service that is marketing's main concern. The rise of the popularity of internet and the widespread of social media, as well as the habits of society to being persistently online, resulted in the necessity to develop stakeholder relations online for reputation development and product placement. Trends show a continuous growth in the number of social media users, as well as smartphone users, which is something public relations and marketing departments must be ready for.
