Google was the most powerful advertising machine ever built.
Starting as a research project from two PhDs at Stanford (Page and Brin), Google became the most scalable advertising machine of our time.

Today Google, rebranded as Alphabet, still generates most of its revenues from advertising, which powers up more than 80% of its revenues in 2021.

Google (now Alphabet) primarily makes money through advertising. The Google search engine, while free, is monetized with paid advertising. In 2023, Alphabet generated over $175B from Google search, $31.51B billion from the Network members (Adsense and AdMob), $31.31B billion from YouTube Ads, $33B from Google Cloud, and $34.69B billion from other sources (Google Play, Hardware devices, and other services). And $1.53B from its other bets.
The hidden revenue generation model is among the most profitable patterns for business models built on advertising. In fact, businesses like Google and Facebook have managed to gain more than $290 billion in 2021 from advertising on their platform, even though many users might not be aware of the mechanisms that drive those platforms.
At the same time, Google has been trying for years also to diversify away from its core businessmodel, placing bets in other areas.
As of 2022, those bets haven’t paid off yet, and in 2021, for instance, the main bets Google (Alphabet), has cost the company over $5 billion.

Of Google’s (Alphabet) over $307.39 billion in revenue for 2023, Google also generated for the first time, well over 1.5 billion dollars in revenue from its bets, which Google considers potential moonshots (companies that might open up new industries). Google’s bets also generated a loss for the company of over $4 billion in the same year. In short, Google is using the money generated by search and betting it on other innovative industries, which are ramping up in 2023.
