Sir David Attenborough, celebrating his 100th birthday, has transformed natural history broadcasting over seven decades. The BBC's most influential broadcaster pioneered wildlife programming since Zoo Quest in the 1950s, creating content that documented climate change's impact on global habitats while setting quality standards that shaped television's evolution through multiple technological revolutions.

His commercial value remains substantial. 320 million viewing hours for Attenborough titles on Netflix (2023-2025) demonstrates enduring audience appeal across generations. The BBC relies on his work to maintain relevance against streaming rivals, with his documentaries like Planet Earth representing the corporation's most expensive nature commissions while driving public engagement and justifying the license fee.

Attenborough's distinctive voice became the BBC's global brand asset, commanding authority even in unseen narration. His ability to make science digestible and emotional has sustained his market value across technological shifts from black-and-white to 4K. The broadcaster's legacy extends beyond content to creating unparalleled commercial value for media partners across platforms.
