The chart is hard to read exact numbers from, there is a table available at the second link. 2008 was the last year that feed accounted for more than 1/2 of corn use (it still accounts for nearly 1/2 today, I'm not trying to be pedantic there, just adding information).
Ethanol is clearly a big enough portion of consumption to be impacting the price of corn used for food, which isn't the same thing as burning edible food, but it's a reason to carefully consider what incentives are created by various government programs.
