Firstly it’s a big company but it’s not that big. Obviously that’s a lot of money but eg in 2006, there were over 200 companies worth more than $30B[1]

Secondly in 2004, the company mostly only did search on the internet, advertising on search terms, and adwords, whereas nowadays google do all sorts of things all over different industries.

The google of today is much larger in terms of employees, market cap, and size than it was in 2004.

$23bn I think is a corp and $1trillion+ is a megacorp? What is a gigacorp? $100trillion+?

"Corporation" is not a unit of measure. A "unicorp" does not have a market cap of $1. "Megacorp" does not use an SI prefix - it just refers to exceptionally large companies. This is the understanding my word choice is based on.

Obviously it's $1,000 trillion

Google was a very large company at $23B, but hardly a stand-out on the Fortune 500. The megacorps which are the focus of discussion - contemporary FAANG et al - are in an entirely different league, by orders of magnitude.

It really doesn't help your case when you have your own views of what a megacorp is that are way out of whack with the rest of the world. I would recommend you write your blog post math style, where you begin with definitions so that people know what you're talking about.

I have added a small edit which clarifies this point. However, I do not consider my definition to be "out of whack with the rest of the world".
