"Pop Art is the use of commercial art as a subject matter in painting, I suppose. It was hard to get a painting that was despicable enough so that no one would hang it – everybody was hanging everything. It was almost acceptable to hang a dripping paint rag, everybody [in America, mainly in New York, 1950s] was accustomed to this. The one thing everyone hated was commercial art; and apparently they didn’t hate that enough either."
