It's actually pretty hard to detect except through indirect means, one of which was to use a flash object to monitor for framerate changes. On-screen objects would render with a higher framerate. Google seems to have built out an API so that you can just explicitly check.
For marketers, this is actually a big thing because it means a key success metric (did people actually see your ad?) can be measured more reliably.
You can disdain advertising or marketing in general and you'd have a point, but what you quoted is actually describing a well thought out solution to a common industry problem.
This stuff is all geared at advertisers who want better tools for designing ads and landing pages, and publishers who want to create ad supported sites more easily. So they are using industry jargon that people in the space (like myself) will be familiar with. Yes it is "marketing to marketers" (not sure about the lesser remark), but that doesn't make it any less specific.
I'm not sure which specific page you are referencing, but this is all technical advertising jargon that means very specific things.
"Viewability" is a technical term referencing whether an impression is viewed by a user. As advertisers increasingly demand more transparency around ad inventory quality from publishers, viewability is a newer metric that the industry looks at. Here's a good starting point from the IAB for how they classify it [1].
Determining whether an ad has been in view has some technical challenges which you might be familiar with if you know much about front-end stuff. At a quick glance of your quote, this references improving the way a pages viewability of ads is measured on mobile by removing the need for Flash for sites to signal "hey, this ad impression is viewable (and thus more valuable)!" Flash bad, this good.
Here's some further reading[2] on the technical challenges from a company that handles inventory where these metrics are a factor.
Look, we get it, you don't like marketing. And yeah, my industry can lay it on thick sometimes, but this is about as poor an example of that as it gets.

Advertising itself is not a bad thing, it's a critical part of any capitalist society. I just don't understand how we got to the point where seemingly every ad is as annoying as it could possibly be, that every ad company is just in a race to the bottom of "how can we be as intrusive and unsubtle as possible."
But I get what you're saying. I feel the same. But like I said, there must be a reason.
Marketers aren't dumb.. they wouldn't invest so heavily in this if it wasn't effective.
So they're just unethical? Your logic can be used to justify a bunch of terrible things.
>Nobody enjoys getting raped, but it is still very popular.. why? Because it still works.
>Nobody enjoys getting scammed, but it is still very popular.. why? Because it still works.
>Nobody enjoys getting robbed, but it is still very popular.. why? Because it still works.
Those are two different distinct forms of marketing, one of which I have no issue with, other than my impending financial ruin.
That said, this is largely about decrapifying the web (getting rid of Flash is a good thing right?) and the parent also crapped all over a profession and industry while proving to be rather uninformed about it. So no, a little negativity isn't called for.
What happens is people only associate advertising with marketing, which is really only one piece of it. Furthermore, they take one type of advertising, with data-hungry and sometimes intrusive online ads, and extrapolate their negative feelings towards that to ALL of marketing. Thus, anyone involved in marketing is a lesser person than them.
Well... That didn't last long.
Including this: "a new JavaScript API in Google Chrome, called Intersection Observer, which provides viewability measurement for your mobile and desktop web placements without the need for Flash. Built directly into the Chrome Browser, Intersection Observer improves viewability coverage for all video and display formats across screens by solving technical challenges associated with mobile viewability measurement. It also provides faster browsing and less battery drain, improving the consumer experience."
I don't use a web browser built by an ad company, but what does this mean in human language?
