  The development of the internet has allowed for the global distribution of
content, redefining media communication and property structures through various
streaming platforms. Previous studies successfully clarified the factors
contributing to trends in each streaming service, yet the similarities and
differences between platforms are commonly unexplored; moreover, the influence
of social connections and cultural similarity is usually overlooked. We hereby
examine the social aspects of three significant streaming services--Netflix,
Spotify, and YouTube--with an emphasis on the dissemination of content across
countries. Using two-year-long trending chart datasets, we find that streaming
content can be divided into two types: video-oriented (Netflix) and
audio-oriented (Spotify). This characteristic is differentiated by accounting
for the significance of social connectedness and linguistic similarity:
audio-oriented content travels via social links, but video-oriented content
tends to spread throughout linguistically akin countries. Interestingly,
user-generated contents, YouTube, exhibits a dual characteristic by integrating
both visual and auditory characteristics, indicating the platform is evolving
into unique medium rather than simply residing a midpoint between video and
audio media.
