Limitations and suggestions for future research
Although the results of this study have useful implications, some limitations must be considered. First, the fact of the blurring differences between consumer generations, particularly the X and Y generations - as well as the fact that each generation has identified an internal diversity. Second limitation refers to the type of marketing channels included in the research. Finally, a limitation also applies to the spatial extent of the study. The above limitations can also serve as some directions of future research – taking into account some other marketing channels and verifying the conclusions referring to other consumer groups. As far as marketing channels are concerned, the mobile channel is undoubtedly worth considering. As the researchers rightly point out, m-commerce is not the same as e-commerce (Maity and Dass, 2014). We believe that there is a great potential of media richness of the online channel for the reduction of consumer risk and uncertainty about the available online information. For this reason, it is worth analysing the virtual worlds and the aspect of transmitting multiple cues interactively in the future research (Chesney et al., 2017). Moreover, the importance of social factors shaping the perception of media richness should be taken into research consideration. According to the social influence, model media perceptions are partially subjective and socially constructed, and not merely based on objective media characteristics (as is the case in the media richness theory) ( Järveläinen, 2007). Consequently, the service supplier does not have a full impact on the perception of media richness of marketing channels. The role of social influence in the media richness perception of each channel should be indicated as another research area.
