    This dissertation addresses various aspects of the term second screen and the challenges involved in the development of this type of application. The term and its characteristics have been clearly delineate by the means of a structured review of literature of 65 publications and an analysis of 19 currently available commercial applications. Furthermore, a content and technical classification were created to facilitate communication and the positing of future research activity in this area. The development of second screen applications is currently associated with a high effort, caused by the redundant implementation of multiple software platforms on both first and second screen side. In order to counteract this double multi-platform problem, an SDK was developed that facilitates the connection and communication process between the different application parts. The functionality of this 2ndS SDK was evaluated as reliable and performant and proven in several functional prototypes, which also served the purpose to examine existing and new forms of second screen interaction. In addition to addressing the technical challenges involved in the development of second screen applications, this work presents several results regarding the optimization of human-computer interaction in this type of application. These include a collection of 55 application components raised and validated in a mixed-method approach and insights into the attention behavior in such scenarios with corresponding recommendations derived from two eye-tracking studies. Furthermore, were concrete design guidelines from existing sources abstracted and evaluated with the help of a user study, and heuristics derived for the domain second screen and extended to a checklist for the efficient identification of problems. The results presented in this work are intended to be used in a usercentered design process and aim to ease the development of second screen applications with optimized interaction, and thereby contribute to their awareness and further distribution

    L'objectiu fonamental de la present tesi doctoral 茅s analitzar l'impacte de la televisi贸 a la carta en les audi猫ncies del prime time a Espanya i, per extensi贸, a la planificaci贸 de mitjans. L'aparici贸 de diferents cadenes de televisi贸 al llarg dels 煤ltims anys ha suposat una fragmentaci贸 de les audi猫ncies en funci贸 de l'oferta televisiva i dels gustos particulars de cada individu entre l'audi猫ncia, que ha arribat a la m脿xima expressi贸 des del moment en qu猫 els espectadors poden triar el contingut que desitgin, en el moment que prefereixin. El catalitzador d'aquesta evoluci贸 en el consum de la televisi贸 茅s la tecnologia en general i internet en concret, que de forma conjunta ofereixen els dispositius necessaris perqu猫 el consumidor de contingut audiovisual pugui accedir a ells de la forma m茅s r脿pida i c貌moda. La rellev脿ncia d'aquesta recerca per a la planificaci贸 de mitjans resideix que aquesta 茅s una de les fases ja no nom茅s m茅s importants del proc茅s publicitari, sin贸 a la qual es destina la major part del pressupost d'una campanya publicit脿ria, i les audi猫ncies representen, per a la majoria de les cadenes actuals, la seva principal font d'ingr茅s. La recerca es recolza en importants elements quantitatius com l'an脿lisi de les audi猫ncies aconseguides pels principals programes en la televisi贸 a Espanya entre els anys 2002 i 2016, i es complementa amb valoracions qualitatives rellevants que inclou les aportacions de professionals que representen a les principals empreses del sector.El objetivo fundamental de la presente tesis doctoral es analizar el impacto de la televisi贸n a la carta en las audiencias del prime time en Espa帽a y, por extensi贸n, en la planificaci贸n de medios. La aparici贸n de distintas cadenas de televisi贸n a lo largo de los 煤ltimos a帽os ha supuesto una fragmentaci贸n de las audiencias en funci贸n de la oferta televisiva y de los gustos particulares de cada individuo entre la audiencia, que ha llegado a la m谩xima expresi贸n desde el momento en que los espectadores pueden elegir el contenido que deseen, en el momento que prefieran.

La relevancia de esta investigaci贸n para la planificaci贸n de medios reside en que 茅sta es una de las fases ya no s贸lo m谩s importantes del proceso publicitario, sino a la que se destina la mayor parte del presupuesto de una campa帽a publicitaria, y las audiencias representan, para la mayor铆a de las cadenas actuales, su principal fuente de ingreso. La investigaci贸n se apoya en importantes elementos cuantitativos como el an谩lisis de las audiencias conseguidas por los principales programas en la televisi贸n en Espa帽a entre los a帽os 2002 y 2016, y se complementa con valoraciones cualitativas relevantes que incluye las aportaciones de profesionales que representan a las principales empresas del sector.The main objective of this doctoral thesis is to analyze the impact of the video on demand in the prime time鈥檚 audiences in Spain and, by extension, in the media planning. The appearance of different television channels over the last few years has led to a fragmentation of the audience in terms of the television offer and the particular interests of each individual among the audience, which has reached the maximum expression since the moment that the viewers can choose the content that they want, whenever they prefer. The catalyst for this evolution in the television consumption is the technology in general and internet in particular, which together offer the necessary devices so that the consumer of audiovisual content can access them in the fastest and most comfortable way. The relevance of this research for media planning is that it is one of the stages not only more important in the advertising process, but also the one that allocates most of the budget of an advertising campaign, and the audiences represent, for most of the current channels, its main source of income. The research is supported by important quantitative elements such as the analysis of the audiences obtained by the main television programs in Spain between the years 2002 and 2016, and it is complemented with relevant qualitative evaluations that include the contributions of professionals who represent the main companies of the sector
