Titstare is a fictional mobile application centred on pictures of men staring at women and their breasts. It was introduced at a 2013 hackathon at TechCrunch's TechCrunch Disrupt conference in San Francisco, California by two Australian developers.[1] Titstare became the subject of public controversy, with the skit being described as symptomatic of sexist attitudes in Silicon Valley's startup culture. Conference organizers later apologized for the misogynistic presentation.
