The solution
The Peruvian Cancer Foundation runs its 'Ponle Corazón' annual fundraising drive on broadcast TV, where reach is the whole game. But prime time — the block where a charity's plea actually reaches the millions whose attention matters — is booked out months in advance by the country's biggest brands; the channel, Latina, had nothing free to donate. The foundation's message was banished to late night and low-audience hours, exactly where an urgent cancer message is wasted.
The obvious responses all fail: bump a paying advertiser to give the charity the slot, and you burn the revenue prime time exists for; keep the charity in the cheap hours, and the drive reaches nobody; or wait for a free moment that never comes. A charity with no media budget and a channel with an already-sold schedule looked like an unsolvable constraint.
Latina found the inventory inside the medium itself: it imperceptibly accelerated prime-time playback by 0.7% — a speed change the human eye and ear cannot consciously notice — so a programme that ran 45 minutes of content plus 15 minutes of ads shrank to 44 minutes, freeing one entire minute that 'didn't exist'. That manufactured minute aired two free 30-second charity spots for several consecutive weeks in the most valuable block on screen, at 0% media spend.
What it achieved
Accelerated prime-time playback 0.7% imperceptibly, shrinking a 45-minute show to 44 to manufacture a free minute for two charity spots in the top block.
Why it worked
Accelerating playback by 0.7% is below the threshold of human perception, so viewers don't notice.
The reclaimed minute is not cut from any existing ad, so no revenue is lost and no advertiser is displaced.
The charity gets a prime-time slot at zero cost, achieving reach that was previously impossible.
The trick works because the schedule is treated as physics, not a fixed ledger, revealing hidden inventory.
What can be applied
When the resource you need is fully allocated, look for hidden slack in the medium's own mechanics—like playback speed—to create new capacity.
Aftermath
The minute put two free prime-time charity spots on air weekly at 0% spend — and won El Sol 2026's Media Grand Prix The technique generalises to any ad-supported medium whose content plays slightly slower than real time: accelerate within the threshold of perception and the schedule itself yields inventory nobody knew existed, letting a no-budget cause buy the slot money supposedly buys outright.
