自2004年以来，播客已成为向全球公众传播科学的分散媒介。然而，到目前为止，还没有大规模的定量研究的生产和科学播客的传播。该研究确定了2018年1月至2月期间可用的952个英语科学播客，并分析了与播客相关的在线文本和视觉数据，并对关键生产参数进行了分类和记录。研究发现，2004年至2010年间，可用的科学播客系列总数呈线性增长，然后在2010年至2018年间呈指数增长。65%的科学播客系列由科学家主持，77%面向公众受众。虽然有大量的主要是单一主题的科学播客系列，但34%的科学播客系列不是专门针对科学主题的。与生物学和物理学相比，化学在科学播客中的代表性可能不足。只有24%的科学播客系列有公开的经济收入。62%的科学播客系列隶属于一个组织;制作的剧集数量（中位数= 24，平均= 96）比独立科学播客系列（中位数= 16，平均= 48）更多。这项研究提供了第一个“快照”的科学播客是如何被用来传播科学给公众观众在地球仪。
Since 2004, podcasts have emerged as a decentralized medium for science communication to the global public. However, to date, there have been no large-scale quantitative studies of the production and dissemination of science podcasts. This study identified 952 English language science podcasts available between January and February 2018 and analysed online textual and visual data related to the podcasts and classified and noted key production parameters. It was found that the total number of science podcast series available grew linearly between 2004 and 2010, and then exponentially between 2010 and 2018. Sixty-five per cent of science podcast series were hosted by scientists and 77% were targeted to public audiences. Although a wide range of primarily single-subject science podcasts series were noted, 34% of science podcast series were not dedicated to a science subject. Compared to biology and physics, chemistry may be under-represented by science podcasts. Only 24% of science podcast series had any overt financial income. Sixty-two per cent of science podcast series were affiliated to an organization; producing a greater number of episodes (median = 24, average = 96) than independent science podcast series (median = 16, average = 48). This study provides the first 'snapshot' of how science podcasts are being used to communicate science to public audiences around the globe.
