The methods of measuring market success and advertising effect are already quite sophisticated and precise compared to the early age of mass advertising, but identifying cause and effect in the world of marketing is still a challenge. There are so many influential factors, and more and more ommunication channels are becoming available for addressing consumers and promoting one’s brand. So how does good old TV advertising stack up in this environment? Has it become obsolete in the age of social media? Does it belong to the half of the advertising that does not work? If you consider both the short- and longterm effects, the answer is an unequivocal no. That was the result of the calculations of a model developed by Seven One Media, GfK Fundamental Research of GfK Verein and GfK TV Audience Research for determining the return on investment (ROI) of TV advertising.
