Let's consider the most recent Whitney, which took place last year. The Wikipedia entry on the Biennial is here, and the Whitney's list of exhibitors in 2012 is here.
There were about 50 artists or groups selected. Of these, only about five dealt with drawing or painting, as best I can tell from the Web site. It seems the the Biennial curators are free to seek what they consider art wherever they can find it. The result is that I find it hard to deny the the American Art Establishment must consider juvenile attempts to be "creative" as the cornerstone of True Art. To me, it's at best a manifestation of public relations in the form of self-promotion by artists that benefits the Establishment by providing grist for displays and commentary.
But why read my screed when you can link to artist information from the Whitney Web site. Below are images from that site for the five artists who more or less were dealing in traditional graphic media. Enjoy!!
