Notable fallouts in marketing and financial market prediction have raised the interest by the scientific community and the business world in Affective Computing (AfC). Automatically recognizing and responding to a user's affective states, AfC shows a great potential to improve companies capabilities of customer relationship management. The aim of this study is to evaluate this filed of research during the last twenty years, identifying for one side its evolution, by the major publications, citations, journals, authors, productive countries, productive institutions, and collaboration patterns; and for another side, identifying its trends through the analysis of research hotspots, burst keywords and areas of research done so far. This bibliometric analysis is based on the science citation index expanded (SCI-E), from the Institute of Scientific Information Web-of-Science, which is now firmly established as an integral part of research evaluation methodology especially within the scientific and applied fields. The results show a significant 4.19 rate of growth in AfC, doubling the number of publications in 4.02 years time. This field of interest is paving the way for creativity and innovation, and provides opportunities for its greater development. The authors expect to contribute to the theory, supplying researchers with new tools and enabling practitioners to improve their marketing strategies, constantly interested in collecting and predicting the attitudes of the consumers toward their products, brands or services.
