In Italy (my country) dubbing is ubiquitous, but it needs some context: we get a lot of foreign content, particularly on commercial channels, and dubbing is quite high quality in this country (or it used to be), with many many professional voices to choose from (many actors are also dubbers), and I know Germany is quite similar.

I'd also say it has been used to spread a more colloquial official use of Italian in the past (well, like all of the TV), which used to be more restricted by higher classes and more official contexts pre-WWII; unlike the UK, we used to speak many unintelligible dialects (we still do, but by now much less), especially outside of the "Italian core" (where dialects are similar to the official language) in central Italy
It's also where we get our doses of "proper" standard Italian with the right accent, as everywhere else (aside from official announcements, advertising) the official language is "watered down" by regional or pseudo regional accents (e.g. news reporters, presenters, actors, informal situations and so on; similar to how BBC doesn't use RP everywhere anymore).
That's also similar to the Germany situation (call it Holy Roman Empire effect lol )

Now dubbing has come under attack in this country as "cultured" people see dubbing as an improper way to translate content, as a lot of intricacies are lost in translation, including voices, and in the past it was even used as a way to censor stuff.
And it's partly correct, but, especially in animation, I can't see it being banned anytime soon; actually anywhere else too, people are just used by listening and not reading subtitles, it's hard to "go back".

The situation is very similar in other dubbing countries, AFAIK

It's also MUCH MUCH better than Russian/Polish lektor by any possible mean, which doesn't make much sense; and by now many channels and especially streaming services carry subtitles and have double language track, so you have a choice
