There are many interesting Google Inc. divisions, and projects that lead these units. For example, Google Research recently presented results of a study of the dynamics of the popularity of different areas of music for the last 64 years. The project was called Music Timeline
manufacturing company information is not out of the top of the charts service Billboard, and data from its own service Google Play Music (information on artists and albums from this service). By clicking on the main directions appear in this musical flow direction, and in the bottom of the chart shows the most popular at a certain time bands and artists who created the music displayed on the flow chart.
It is worth noting that in the infographic presented "Good Corporation", there is no classical music. The reason for this - the cataloging of classical music not by recording date (in most cases the reason is clear, the date goes far back into the past, at a time Older than 64 years).
Google Research is to conduct further research and all sorts of changes in the world of music. For the current study, all of its outcomes is graphically well understood by all.
