Kalev's latest Forbes piece features a city/landmark-level map visualizing the every location on earth mentioned at least 5 or more times on American television news shows monitored by the Internet Archive over the last 6 years.
Creating this map required just a single line of code in Google BigQuery and just 4.8 seconds to complete and just a few more seconds to import directly into CartoDB for the final interactive clickable map.
