People who communicate health and risk information are often trying to determine new and innovative ways to reach members of their target audience. Because of the nearly ubiquitous use of mobile phones among individuals in the United States and the continued proliferation of such devices around the world, communicators have turned to mobile as a possible channel for disseminating health information. Mobile health, often referred to as mHealth, uses mobile and portable devices to communicate information about health and to monitor health issues. Cell phones are one primary form of mHealth, with the use of cell phone features such as text messaging and mobile applications (apps) often used as a way to provide health information and motivation to target audience members. Text messaging, or short message service (SMS), is a convenient form for conveying health information, as most cell phone owners regularly send and receive text messages. mHealth offers benefits over other channels for communicating health information, such as convenience, portability, interactivity, and the ability to personalize or tailor messages. Additionally, mHealth has been found to be effective at changing attitudes and behaviors related to health. Research has found mobile to be a tool useful for promoting healthy attitudes and behaviors related to a number of topic areas, from increased sexual health to decreased alcohol consumption. Literature from health communication and research into mHealth can provide guidance for health communicators looking to develop an effective mHealth intervention or program, but possible concerns related to the use of mobile need to be considered, such as concerns about data security and participant privacy.

Photography has been a practical reality for about 190 years, and, from its beginnings, journalism seemed like a natural application of the medium since most people believed that the photograph was an objective representation of reality. During the years since the first surviving photograph was produced in a camera, the evolution of photojournalism has been driven by a combination of technology, public demand, and a passion for the profession by its practitioners. In the first decades after that initial photograph, improvements in lenses, negatives, and prints made photographic reportage of the Crimean War (1853–1856) and the American Civil War (1861–1865) possible. The British and American populaces created immense markets for war images, and entrepreneurial photographers such as Roger Fenton and Mathew Brady provided them. Technological advances in cameras, lenses, film, lighting, photographic reproduction methods, and an ability to transmit photographs worldwide continued to advance the boundaries of photojournalism throughout the 19th and 20th centuries. The topics of that work were mostly motivated by public demand. Wars, politics, photographs of “exotic” cultures from around the world, sports, everyday features, and celebrity portraits provided popular themes and continue to do so into the present, but photojournalists have also pursued subjects that they deemed important to humankind though not necessarily popular. Many have produced social, political, environmental, and cultural documentaries that challenge the status quo. Some have challenged this work as being outside the bounds of “objectivity,” but the usefulness of this argument has been rejected by many in the profession. Legendary photojournalist W. Eugene Smith, for example, stated succinctly, “there is nothing objective about journalism.” The final decade of the 20th century brought the evolution of the digital camera. Today’s photojournalism is almost exclusively a digital endeavor. The transformation of photography from analog to digital has revolutionized photojournalism in terms of workflow, mobility, transmission of images, ethics, image availability, and the question of “who is a photojournalist?” Finally, the gradual mutation of the term “photojournalism” to “visual journalism” denotes a transformation of the medium itself from the still image to a combination of still and moving images or perhaps exclusively moving images in the future. This, in turn, may fundamentally change the ways in which photojournalistic stories are told and experienced.

Two dominant approaches underline the theory, practice, and methodology of global journalism. The first approach captures the various ways that journalism is practiced in different countries. This is reflected in the burgeoning field of comparative journalism studies. The second approach examines the underlying notion of globalization of the interconnected nature of the world and of global journalistic practices that not only relativize the significance of the nation state but also highlight the forces that shape the global village. Each of these perspectives has implications for journalism practice and how the world is understood. Each is influenced by complexities of the existing environment in which journalism is practiced, such as sociocultural practices and barriers, as well as economic, institutional, structural, legal, and political forces that inform journalism at national and international levels. Regardless of the differences, the two approaches are interrelated in various ways. They examine the interlocking relationship between journalism and globalization; factors that influence global news flows and foreign reporting; diverse journalistic practices and modes of education; and global journalism ethics. Altogether these perspectives provide rich analytical insights and background into the past, current, and emerging issues that inform global journalism.

Ehealth, also known as E-health, is a relatively new area of health communication inquiry that examines the development, implementation, and application of a broad range of evolving health information technologies (HITs) in modern society to disseminate health information, deliver health care, and promote public health. Ehealth applications include (a) the widespread development of specialized health information websites (often hosted by government agencies, health care systems, corporations, professional societies, health advocacy organizations, and other for-profit and nonprofit organizations); (b) the widespread use of electronic health record (EHR) systems designed to preserve and disseminate health information for health care providers, administrators, and consumers; (c) an array of mobile health education and support applications that have often been developed for use with smartphones; (d) mobile health behavior monitoring, tracking, and alerting equipment (such as wearable devices and systems imbedded in vehicles, clothing, and sporting equipment); (e) interactive telemedicine systems for collecting health data and delivering health care services remotely; (f) interactive adaptive tailored health information systems to support health education, motivate health behaviors, and to inform health decision making; (g) online social support groups for health care consumers, caregivers, and providers; (h) health promotion focused digital games to engage consumers in health education and train both providers and consumers about health promoting procedures; (i) dedicated computer portals that can deliver a variety of digital health information tools and functions to consumers, caregivers, and providers; and (j) interactive and adaptive virtual human agent systems that can gather and provide relevant health information, virtual reality programs that can simulate health environments for training and therapeutic purposes, and an ever-increasing number of digital applications (apps) for addressing a range of health conditions and activities. As information technology evolves, new ehealth applications and programs are being developed and introduced to provide a wide range of powerful ehealth systems to assist with health care and health promotion. Ehealth technologies have been found by many researchers, practitioners, and consumers to hold tremendous promise for enhancing the delivery of health care and promotion of health, ultimately improving health outcomes. Many popularly adopted ehealth applications (such as health websites, health care portals, decision support systems, and wearable health information devices) are transforming the modern health care system by supplementing and extending traditional channels for health communication. The use of new ehealth applications enables the broad dissemination of relevant health information that can be personalized to the unique communication orientations, backgrounds, and information needs of individuals. New ehealth communication channels can provide health care consumers and providers with the relevant health information that they need to make informed health care decisions. These ehealth communication channels can provide this information to people exactly when and where they need it, which is especially important for addressing fast-moving and dangerous health threats. Yet, with all the promise of ehealth communication, there is still a tremendous amount of work to be done to make the wide array of new ehealth applications as useful as possible for promoting health with different audiences. This article describes the current state of knowledge about the development and use of HITs, as well as about strategies for improving ehealth communication applications to enhance the delivery of health care and the promotion of public health.
