5.1 Investigated research fields within location-based advertising researchEvaluating the field of the publications’ outlets showed a relatively high ratio of technology-oriented publications (47 out of 66) compared to publications taking a business perspective (19 out of 66; cf. Table 3). These ratios may be due to the fact that technical feasibility provides the basis for further research on LBA from a marketing perspective. Accordingly, an increase of advertising studies in the field of LBA is to be expected, once technical challenges (e.g., indoor positioning) and privacy challenges (cf. Haddadi et al. 2011) are overcome. The number of journal publications compared to the number of conferences (29 journals versus 37 conferences; cf. Table 3) hardly allows for any general LBA-relevant conclusions. Interestingly, half of theanalyzed publications have been published in technically oriented conference proceedings (33 publications), which may be interpreted as an indicator that the topic of LBA on mobile devices is (still) in the hands of technically oriented scientists. While research in LBA has its roots in technically oriented disciplines, it is important that research teams have competences in marketing to investigate marketing-related problems of LBA, for example. We conclude from the large ratio of technically oriented publications that collaboration between technically oriented and non- technically oriented disciplines has not yet taken up in the research field of LBA on mobile devices.
