I'm being very clear. A language with a big company behind it the likes of Google, Facebook, Microsoft etc. I have defined it two times now. That there are some vendors which make money with a language is very different.
Advertisement is a subset of marketing. Back in the day when Go was "new" You saw daily posts on many programmer focused communities about it. Google bankrolled the entire development of Go. Blogposts of many googlers talking about the language. Google sponsored Go events. The positive image of Google itself at the time of Go initial introduction.
You try to weasel me towards C# and Java when those are not two language I even have mentioned. But since you want to hear about. Yes both of these were also heavily marketed.
But if the big company behind it doesn't do anything, what difference does it make?
Or, if the big company doesn't do anything more than is done for other languages (Rust, say), what difference does it make? Is Rust marketed in the same way Go is? Per your definitions, I would say yes, even though the Mozilla Foundation isn't a big company.
But then, is Haskell marketed in the same way? I see lots of posts on it, at least here. Lots of blogposts on it. But there's no big company, or even foundation, behind it. Is that marketing?
Why do you define a set of actions as marketing when people who work for Google do it, but not when others do it?
