What is this?
Jeopardy N-Grams lets you measure the frequency of specific phrases in Jeopardy! clues since 1985. When you search for a phrase, J-Grams graphs how common that phrase has been over time. The project was heavily inspired by the Google Books Ngram Viewer

How many clues are searched?
About 250,000 Jeopardy! clues from 1985 through today. The correct answer for each clue—not in the form of a question, i.e., without the "Who is...?" preamble—are also searched. So are categories.
What about punctuation and case sensitivity?
J-Grams is not case sensitive. Most punctuation is stripped out for you automatically, so you don't have to worry about it. Ampersands (&) are not stripped out, so include them if you're looking for law firms!
What does the y-axis mean exactly?
The y-axis represents the frequency of each phrase, as a percentage of all phrases that contain the same number of words. For example, if you search for this woman, the graph shows the number of times those words appear in exact order, divided by the total number of 2 word phrases in all of the articles
