If you read up on the topic the Nielsen ratings data is highly questioned by all the stakeholders, especially the broadcast networks, carriers, and advertisers paying rates based on the Nielsen data. There are a lot of articles out there covering the topic.
The stakeholders have all sort of agreed to continue using Nielsen because they don’t have a better alternative to replace it.
I would hope and expect the Nielsen ratings are more accurate than Forbes, but they still have their warts.
Yes, as I've said in this thread, Nielsen is the standard -- if you want to read up on more recent developments:

Note: The #1 in ratings/viewership in the country the NFL having zero interest in anything other than Nielsen. That alone kills any alternative options. If you don't have the NFL then you're not really in the business, especially since sports ratings/viewership is most popular and NFL is most popular (obviously) in that group.
Twas hilarious when NBCU, who has been the biggest complainer of Nielsen, hyped up all the alternatives they were/are going to use then renewed with Nielsen in the end because it's the standard and what matters in the industry.
So exactly what I said:
"Forbes valuations are guesstimates of what's behind the curtain while Nielsen data
is what's behind the curtain.
If you're buying a sports team you don't use Forbes #s, you want to see the actual books.
If you're buying ad spots, you want to see the Nielsen data."
Nielsen data would be the equivalent of "the books." In other words, it's what matters. Whether anyone trusts the numbers isn't the point, the point is that it's the currency used. So regardless of when and what networks complain or when someone with an agenda (not you) wants to say ratings don't matter because they don't personally trust Nielsen numbers. That's not how the business works and this is the business section of the forum. Nielsen is what is used, that's the releveant data. Past, present and for the future until someone comes up with something better --been many attempts at 'something better' and all of them failed, or currently are in the process of failing (cost cutting/layoffs) and/or are so irrelevant that no one has ever heard of them.
