GDELT Summary About

Television Comparer

Below is a visual dashboard summary comparing broadcast television news coverage of your search using data from the Internet Archive's Television News Archive. While the index is updated every 15 minutes, broadcasts take 24-48 hours to become available for search, so results for the past two days are incomplete. Refresh this page again in 15 minutes to see the most recent updates. Displays work best in Google Chrome.

More Info.

All visualizations are powered by the GDELT Project's TV 2.0 API using data from the Internet Archive's Television News Archive. Technical users will find "export" options on each of the visualizations on this page that allows them to download the underlying CSV/JSON data for further visualization/analysis and to view the HTML code that allows them to embed each individual visualization on their own web page - the embedded visualization will update each time it is viewed/refreshed to display the most recent data as of 15 minutes prior (though broadcasts take 24-48 hours to become available for search). All comparison visualizations make use of the TV 2.0 API's JSONP output capability and perform all comparison/merging activity entirely in the browser at display time.

Timeline Merge

---

The display below merges the volume timeline of each of your searches and displays them on the same combined results timeline, making it easy to compare coverage across topics.

Move your mouse over the timeline to see the value for a given day/hour. You can also zoom into a particular time period by clicking on the timeline and dragging to the right or left to select that date/time range. The entire Television Comparer display will then refresh to reflect just coverage from that zoomed-in time period.

Click on the Export button at the top right of the visualization to save it as an image, download the underlying data as CSV for further statistical analysis or get the code to embed it on your own web page. Note that unlike the other GDELT Summary visualizations, the display below is generated entirely inside your browser on page load.
