What Did Our Submarine Cable Map Glance Like in 1999?


The TeleGeography Submarine Cable Map is our longest-running map project. We started producing submarine cable maps in 1999, and we’re still going strong 25 years later.

Just for fun, let’s compare the very first edition—called the Global Communications Cable and Satellite Map—to this year’s Submarine Cable Map.

Here’s a side-by-side comparison of the two:

1999-2024 Maps

The 1999 Global Communications Cable and Satellite Map (left) focused primarily on the physical infrastructure of submarine cable systems and geostationary satellites, chronicling how advances in fiber optic technology allowed for submarine cables to surpass satellites as the backbone of modern telecommunications.

Throughout the early 2000s, the team found themes that we’ve continued to carry throughout all our maps: data about submarine cable bandwidth growth, different prices that are available on submarine cables, and the cost to build these cables. 

Our latest version, the 2024 Submarine Cable Map, explores global connectivity from the sea to the cloud, depicting 559 cable systems and 1,636 landings that are currently active or under construction. At the bottom of the map, you’ll find additional insights on cable construction, cable investments, and cloud infrastructure.
