Marilyn Minter's Commercials from 1989/1990.
The billboards are an outgrowth of Minter's interest in blurring the boundaries between fine art and commercial art, co-opting commercial genres and spaces for her artistic practice. In 1989, she bought 30-second commercial spots to show her "Food Porn Commercials" that aired during David Letterman, Arsenio Hall, and a Nightline interview with Ted Koppel and Henry Kissinger. (They were cheaper than art magazine ads.) The groundbreaking and unusual artwork/commercial featured quick clips of the artist at work in her studio without directly promoting anything. It caused so much confusion that Los Angeles TV stations added a disclaimer.
