For most of us, telecommunications infrastructure is largely invisible—only noticed when something goes wrong and we lose Wi-Fi or phone signal. Allison Kirkby wants to change that.

As CEO of BT, the Most Powerful Women honoree is overseeing one of the biggest infrastructure transformations in the U.K., from fiber expansion to the country’s shift away from legacy landlines. But she is also trying to make a deeply technical business feel culturally relevant again.

For Kirkby, these flagship moments that bring together millions of people are more than simple branding exercises; they are live demonstrations of the power and reliability of the digital networks underpinning modern life.
