Using our new BigQuery + Bigtable GCS digital twin, we can look across the entire Internet Archive's TV News Archive to explore just how large it is. In all, the Archive consists of 27.8 billion seconds (463.5M minutes / 7.7M hours) of airtime from 10.9 million broadcasts (131,624 distinct show names) across 327 channels from more than 50 countries and territories in over 150 languages and dialects spanning nearly a quarter century, making it one of the largest global archives for journalists and scholars to understand how the world's television news outlets have covered the planet's biggest stories of the millennium's first quarter-century.
