AI is not just the future, it is already reshaping how news gets written, edited, and delivered. As a media giant, the BBC provides a crucial example for examining this significant shift in AI in journalism.

In this episode, we explore 13 years of BBC AI content, spanning 2012 to 2025, using the isFake.ai AI detection platform to analyze trends and create a comprehensive database of AI generated news detection patterns. Our research tracked AI probability scores, publication dates, and article lengths.

The analysis revealed a dramatic shift corresponding directly with the release of major language models like GPT-3. The 2020 transition year marks a clear breakpoint where AI detection scores jumped sharply.

We also examine the critical article length correlation. Our findings show a statistically significant negative correlation: Longer articles usually have lower AI probability scores, suggesting that complex investigations and in-depth reports still rely heavily on human expertise. Conversely, shorter pieces are often flagged as AI, reflecting AI's utility for quick updates and summaries. The analysis also tracks the evolution of diverse AI model signatures over time.
