How do videos spread?
Millions of videos on YouTube are viewed every single day. Have you ever wondered how the most popular of them get spread around the world?
On the right side, this map represents a broad overview of where the most popular videos get spread. The source country (yellow) is where the videos first became popular (making the Top 50 list for that country on a given day). The red circles represent countries where those videos also made it to their Top 50 Video list. The size of the red circle correlates with how many videos made Top 50 after they became viral in their source country. The interval between the particles are scaled by the frequency of video propagation on the paths.
Who Spreads the Most Videos?
Countries X Number of Countries Reached
The heatmap allows the user to make comparisons between the reach of videos coming from the 74 countries represented in this entire visualization. The Y-axis represents the reach of the number of videos from the source country - for instance, if a video became popular in country X first and then the video became top 50 in countries W, Y, and Z, the reach of the video is 3. Reach is a measure of in how many countries this video has reached top 50. This visualization ignores the number of days any particular video was popular. Hover over each block to get more details on each country's video reach.
This visualization shows the proportion of videos that are shared in the respective top 50 lists in two countries for each different category. The yellow bars represent videos that were only top 50 in the left country. The white bars show videos that were top 50 in both countries and red bars show represents the videos that became top 50 only in the country on the right. Countries that speak the same languages share a bigger proportion of shared videos, especially in music - try comparing Spain and Argentina or Brazil and Portugal.
