TF1's OR partnership added €20M a year by selling airtime as a perishable asset
Bouygues' OR lab spent 15 years optimizing TF1's ad airtime and internet inventory, adding an estimated €20M in annual revenue.
TF1 · Bouygues e-lab
the move
French TV channel TF1 sells airtime that is worthless the second a slot has aired. For 15 years its corporate OR partner, the Bouygues e-lab, worked on projects covering both the television and internet businesses, giving TF1 quicker and better answers to advertisers' requests.
The models focused on using limited, perishable airtime inventory well: deciding which advertiser gets which slot, how to value audience, and how to respond fast enough that deals are not lost.
TF1 estimated the resulting revenue increase at about €20 million per year. The paper credits the partnership's continuity and embedded teams as the key to making the models stick.
why it works
- Airtime is perishable: unsold slots vanish, so allocation models convert inventory into revenue instead of letting it expire.
- Fast responses to advertisers' requests win deals that slower manual processes lose.
- A 15-year partnership let models accumulate knowledge of how the business actually works.
what transfers
When the product expires at a fixed moment, the selling problem is inventory management: optimize allocation against perishability, and the same airtime earns more without any new capacity.
what came after
The partnership continued and expanded into TF1's internet business. The TF1 engagement became a published reference case for embedding OR teams inside a media company, with TF1 attributing about €20 million a year in added revenue to the work.
