I would not bet on Nielson if Google were to get the knife out and come for their market; but the ugly thing about spelling errors is that, since show names can(and I think some do) use deliberately incorrect spellings, you can’t just spell-check your way out of it.
A naive spell checker can transform all misspellings into their closest correct equivalent, but can’t distinguish between errors and intent.
Someone with lots of statistical data, like Google, can transform all inputs into the outputs people like you most often intended; but can still only get the answer right if the right answer isn’t the improbable one in this case (think of the occasional topic that is virtually unsearchable without copious use of quotation marks and exclusion modifiers and such because it overlaps with something that uses most of the same strings and is vastly more popular).
They would certainly be right more often than the naive case or the pitifully obtuse case; but when dealing with inputs that may be malformed so as to be underdetermined, overdetermined, or both; there is only a way to the more plausible answer, not a path to the correct one(because there may well be zero or more than one correct answers).
