Comment Meta/Alphabet (Score 1) 119
Meta (Facebook/Instagram/Threads) and Alphabet (Google/YouTube) has machine learning to train models that then their ad networks use inference on to deliver you advertising across the entire internet.
This is one of those R&D cost things. Those companies entire bottom lines depend on how competitive their advertising networks are. They invest in AI/ML and get the return elsewhere invisibly.
Is it truly paying off at the scale they're investing in right now? Well, maybe... but it certainly is no where near the losses being advertised right now.
