On 16 July 2010, Instagram’s co-founder and CEO Kevin Systrom (USA) uploaded a picture of a golden retriever to the app, which was then known as “Codename”. The names of the dog and its owner are not known, but the foot in the picture belongs to Systrom’s girlfriend. The photograph was taken at a taco stand named Tacos Chilakos in Todos Santos on the Baja California Peninsula in Mexico. The app was made available to the public in October that year, by which time it had been retitled "Instagram".
