Social media
Banksy posted the entire event on his social media and labeled it with the caption ‘going, going, gone’. It was obvious that he was trying to make a statement about the art industry and how he thought it was ridiculous. All his fans praised him for his actions and again said it was a stroke of genius.
Banksy just had his finger on the pulse and knew what the masses were thinking. Most people believe that art that is overpriced is ridiculous at the end of the day and Banksy was aware of this. By shredding his own painting, his experiment worked and people were having all types of reactions and conversations about it.
