Trends in over the top (OTT) research: a bibliometric analysis

The purpose of this paper is to examine current trends in over the top (OTT) research through bibliometric analysis of Scopus and Web of Science indexed publications. This study attempted to identify the thrust areas that may be addressed through future research initiatives.

This study included bibliometric analysis of research articles published on OTT domain for a time period ranging from 2011 to 2021. The authors were able to extract 137 unique articles from selected databases with inclusion criteria limited to social sciences only. The retrieved data is then analyzed using the R studio and VoSviewer user interfaces. Finally, discussions on citations, keywords, authors and source contributions toward the development of field were presented using descriptive and visual displays.

OTT as a research theme has gained wider acceptance recently. However, there is a scarcity of studies on the subject. The authors discovered that previous studies in the field had focused on technological aspects of the domain thus leaving a plethora of opportunities for future researchers to explore. In this regard, the findings enlisted few unexplored domains specific to OTT that require immediate attention of the researchers and stakeholders. It was suggested to investigate the field from marketing, behavioral, regulatory, social and quality aspects so as to broaden its scope.

To the best of the authors’ knowledge, this is going to be the first bibliometric study ever conducted on OTT research. This study may be considered unique in identifying current trends in OTT research and recommending a course of action for future researchers.
