This chapter will define the genre of digital poetry and its components and also include a brief discussion of the history of digital poetry. As Hayles (How We Think, Digital Media and Contemporary Technogenesis. Chicago: University of Chicago Press, 2012: 13) tells us, digital texts can no longer be regarded as singular standalone objects rather they are constantly changing assemblages in which inequalities and inefficiencies in their operations drive them towards breakdown, disruption, innovation and change. The sharing economy of the internet, as it is termed, means that contemporary cultural content such as poetry cannot be separated from the communities and platforms that both form and read them. This chapter draws out the problematics of definition of the hybridic object that is a digital poem in order to situate the following chapters within an identifiable framework of practice.
