Territory marking describes the canine behavior of marking places with scent and participating in sniffing formerly marked territory. This is also applied to Foursquare, as it is a territory marking participation architecture such as Foursquare or Google Search Results. In the analog space, this is shown in billboards, brands and logos in public spaces such as Subways, and private spaces such as sporting events. It bleeds into digital space when it is photographed or televised, expanding the marked space and the brand's reach.
