Social media have become useful tools for audiovisual promotion, especially to reach niche audiences. Twitter promotional strategies have been widely studied, yet other growing platforms such as Instagram have been less analyzed. This paper examines the Instagram promotional strategies of two pay-per-view platforms (HBO and Netflix) in two markets (the United States and Spain). A total of 731 messages, posted between May and November 2017, were analyzed to identify their formal features, objectives, and their content's emotional and cognitive elements posted on HBO and Netflix's Spanish and U.S. accounts.The results showed acute differences between how HBO and Netflix use their Instagram accounts in the two markets (Spain and the United States). The Spanish accounts mostly provided information, while the American accounts both provided information and promoted program content. Posts from U.S. accounts more frequently included links to social media, particularly to celebrity accounts. Spanish accounts relied more on diegetic images, whereas U.S. accounts emphasized non-diegetic and off-set images.Netflix used humor more than HBO did, and a stronger focus on celebrities. Humor and positive tone were found to be linked to higher engagement.

International audienceThis paper presents the communication strategies on Facebook of non-profit organizations from four Hispanic speaking countries where cancer is the second cause of death. The content analysis of the messages posted during three months shows how these organizations are more active when they are celebrating cancer days or when a campaign is taking place. Most of the messages address the disease in general instead of a specific one. They aim to inform and create awareness among their followers and they use images as their main resource. Followers prefer to use the " like " button or to share posts instead of making comments.Este artículo aborda la estrategia de comu­ nicación en Facebook de asociaciones sin ánimo de lucro pertenecientes a cuatro países de habla hispana donde el cán­ cer es la segunda causa de mortalidad. El análisis de contenido de los mensa­ jes publicados durante tres meses revela una mayor actividad durante periodos de celebración de lucha contra el cáncer o diferentes campañas. La mayoría de los mensajes se refieren al cáncer de forma general sin abordar uno específico; infor­ man a los seguidores y crean conciencia en ellos, empleando como recurso prin­ cipal la imagen. Los seguidores prefieren darle a " Me gusta " o " Compartir " antes que comentar

This study examines Spanish academics’ motives for using social networking sites (SNS) and their perceptions regarding the limitations of and drawbacks to social media. We analyse 18 in-depth interviews conducted with Spanish university professors chosen according to their disciplines, academic ranks and level of use. Our findings confirm prior research based on the uses and gratifications theory. Thus, we conclude that SNS are used for managing content, identifying experts in a researcher’s field of knowledge. In addition, academics need to manage different personal identities in each SNS they use.
