The winners of the 2014 World Press Photo Multimedia contest have been announced and the work represents a staggering array of subjects and documentary styles. The international jury selected first, second and third place winners in three categories: Short Feature, Long Feature and Interactive Documentary.  

The winners in the short and long form categories include visually stunning and compelling looks at topics ranging from dementia to civil unrest. The interactive documentary category included a look at the declining rural communities in America, the NSA surveillance documents and the history of towering apartment buildings. 

Winner in the Short Feature category was Marco Casino's 'Staff Riding', a look at train surfing in South Africa (see above). The winner of the Long Feature was Emim Özmen’s 'Witnessing Gezi', which looked at the causes and conflicts of student uprisings in Turkey. The Interactive Documentary prize went to the New York Times for 'A Short History of the Highrise'. 

Each category's top-three submissions can be found on the World Press Photo page
