In a society predicated on information, the media has a pervasive presence. From government policy to leisure television, the information age touches us all. The papers collected in this book constitute some of today's leading analyses of the information industry. Together, these essays represent a needed foundation for understanding the present state and future development of the mass media. Current trends in communications as well as media impact on public opinion are studied and reported on. Topics include successful migration of EPON to WDM EPON; Kony 2012 and the invisible children's challenge of social media campaigning and digital activism; the process of liberalisation of the telecommunications market in the Republic of Serbia; wavelength multiplexing for super resolved imaging and spatial data compression; social media challenges for professional writers; transmission behaviour in ad hoc networks; and WSM dispersion-managed soliton transmission systems.
