The telecommunications research company TeleGeography created this map, and you can see the full interactive map at their website. Although satellites are used for broadcast and for connecting some rural communities to the rest of the world, cables form the arteries of our global communications and they are only growing. CNN has an interesting interview with TeleGeography research director Alan Mauldin about the cables, including their variable performance and how human and geological interference have left some countries with impaired Internet access.
