This study investigates how young adults use news and location-based services on their smartphones, in addition to examining how many news organizations offer mobile news apps with geo-location features. Based on the survey findings, young adults are consuming news on their smartphones. Furthermore, there is a high use of location-based services by smartphone consumers, but news organizations are only using geo-location features in their mobile apps for traffic and weather. This study highlights that a gap exists between what news consumers, particularly young adults, are doing and using on their smartphones and what news organizations are able to provide.

This paper presents a theoretical reframing of journalism as a fundamentally mobile practice and outlines a research agenda for studying the politics of mobility in journalism that is centered on the everyday work of journalists. Our reframing draws on geographer Tim Cresswell's work on the six components of a politics of mobility, which are motive force, speed, rhythm, route, experience, and friction (Cresswell, T. 2010. "Towards a Politics of Mobility." Environment and Planning D: Society and Space 28 (1): 17-31). Cresswell poses six key questions about mobility, and rephrasing them to to fit journalists, we get why do journalists move?; how fast do journalists move?; according to what rhythm do journalists move?; what route(s) do journalists take?; how do journalists feel when they move?; and what stops/impedes the movement of journalists? These questions entail a research framework concerned with the different conditions of movement for different bodies, thus drawing attention to previously under-studied areas of journalism studies.

This article explores two different but complementary theoretical approaches to frame innovation in online media: actor-network theory and community of practice.The principles and key concepts of each are presented and their suitability to the analysis of innovation in journalism is discussed through four newsroom cases.The findings demonstrate that these theories are efficient tools to understand and analyze the actors involved in innovation decisions in the newsroom, the dynamics of the negotiation and learning processes among the journalists and the factors constraining and fostering evolution when innovations are implemented or disregarded in the newsroom.

While critics of Twitter, the most popular microblogging application, dismiss the service as frivolous, proponents tout a variety of educational, political and commercial uses. Drawing from social construction theories of technology, this research uses the grounded theory approach to analyze press coverage of this emerging technology from 2006 through the first months of 2009. While the specifics of Twitter may be new, this research demonstrates that the public response to this web tool is similar to the public reaction to earlier communication technologies including the telegraph, radio and the internet. Despite vocal skepticism from some, the research shows newspapers, magazines and blogs have promoted and actively encouraged Twitter's diffusion.
