The Red de Popularización de la Ciencia y la Tecnología en América latina y el Caribe (RedPOP) (Latin American and Caribbean Network for the Popularization of Science and Technology) was created 25 years ago as an expression of a movement that started in the 1960s in favour of a scientific education. The purpose of this movement was to incorporate science into the general knowledge of the population by communicating science through different media, products and spaces such as museums and science centres. Since then, the movement has acquired considerable strength in Latin America and RedPOP has been a key factor to the development of this activity in the region, although several challenges still have to be addressed.

Access to high quality evaluation results is essential for science communicators to identify negative patterns of audience response and improve outcomes. However, there are many good reasons why robust evaluation linked is not routinely conducted and linked to science communication practice. This essay begins by identifying some of the common challenges that explain this gap between evaluation evidence and practice. Automating evaluation processes through new technologies is then explicated as one solution to these challenges, capable of yielding accurate real-time results that can directly feed into practice. Automating evaluation through smartphone and web apps tied to open source analysis tools can deliver on-going evaluation insights without the expense of regularly employing external consultants or hiring evaluation experts in-house. While such automation does not address all evaluation needs, it can save resources and equip science communicators with the information they need to continually enhance practice for the benefit of their audiences.

Taking the International Science in Popular Culture conference as a starting point, this editorial considers audiences for cultural products, considering the size of audiences (from blockbuster films, to intimate science slams), their pre-existing (or lack of pre-existing) interest in the subject and what this might offer the field of science communication.
