A talk by Joe Armstrong I watched recently indicated that around 50% of 3G and more than that of 4G infrastructure uses Ericsson technology, specifically with swoftware written in Erlang. He made a joke about 'sweating over every bit' sent over the network and then complaining that all the apps are going crazy with their JSON.

[incepted]

Erlang is mentioned only once in this entire article, and it's in the "See also" section. Nothing in this Wikipedia article supports the claim that Ericsson uses Erlang at all.

Sorry, you're right. I was more indicating at the fact that they power a huge amount of the infrastructure of mobile and telecoms.

Here's some sources that indicate that Erlang is still in daily use at Ericsson:

I'm sorry I can't find the exact video I saw from Joe, but he's generally quite proud of the reach of Erlang so you'll find him stating the facts about how much of the mobile and telecoms infrastructure it supports in a few of his videos! I hope that helps.
