The Global Media Internet Concentration Project examines the concentration of the communications and media in countries around the world.
The latest data for Australia have recently been released, and they show just how big Google is here.
Alphabet (Google's parent company) had 2022 revenue in Australia of A$7.9 billion.
That revenue is only exceeded by Telstra, and is bigger than Optus and NBN Co. It's also bigger than the revenues of News Corporation and Nine Entertainment combined.
The network media economy includes telecoms and internet infrastructure, digital and traditional publishing and internet-based companies. The 2022 revenue of this economy in Australia was $69 billion. The revenue of the top four telecommunications operators accounted for half of that.
