Unless the Nelson company (which is for TV) is under a different name on the forums you are wrong. If this is a different company, they are too cheap to hire them.
I've never heard of "the Nelson company", but The Nielsen Company does a lot more than just TV research. I took a survey for them on consumer products just a couple of weeks ago.
Their mission statement is "In 100 countries around the world, Nielsen provides clients the most complete understanding of what consumers watch and buy."
They spend more of their time doing market research than TV research, it's just the TV research that gets the most coverage from the TV press, for reasons that should be obvious.
