Library as Laboratory Recap: Opening Television News for Deep Analysis and New Forms of Interactive Search
Posted: Sat Jul 05, 2025 6:10 am
Watching a single episode of the evening news can be informative. Tracking trends in broadcasts over time can be fascinating.
The Internet Archive has preserved nearly 3 million hours of U.S. local and national TV news shows and made the material open to researchers for exploration and non-consumptive computational analysis. At a webinar April 13, TV News Archive experts shared how they’ve curated the massive collection and leveraged technology so scholars, journalists and the general public can make use of the vast repository.
Roger Macdonald, founder of the TV News Archive, and Kalev Leetaru, collaborating recent mobile phone number data data scientist and GDELT Project founder, spoke at the session. Chris Freeland, director of Open Libraries, served as moderator and Internet Archive founder Brewster Kahle offered opening remarks.

“Growing up in the television age, [television] is such an influential, important medium—persuasive, yet not something you can really quote,” Kahle said. “We wanted to make it so that you could quote, compare and contrast.”
The Internet Archive built on the work of the Vanderbilt Television Archive, and the UCLA Library Broadcast NewsScape to give the public a broader “macro view,” said Kahle. The trends seen in at-scale computational analyses of news broadcasts can be used to understand the bigger picture of what is happening in the world and the lenses through which we see the world around us.
In 2012, with donations from individuals and philanthropies such as the Knight Foundation, the Archive started repurposing the closed captioning data stream required of all U.S. broadcasters into a search index. “This simple approach transformed the antiquated experience of searching for specific topics within video,” said Macdonald, who helped lead the effort. “The TV caption search enabled discovery at internet speed with the ability to simultaneously search millions of programs and have your results plotted over time, down to individual broadcasters and programs.”
