$$\text{Superbowl Sundelay}$$

===

The Super Bowl Halftime Show is pop culture's biggest stage, with tens of thousands of people watching in person in the stadium and $100$ million viewers watching the TV broadcast.

Let's assume that the stage is set up in the middle of the field and that the sound system is approximately $100\text{ meters}$ (about $300\text{ feet}$) away from the last row of seats in the stadium and we also assume that the viewer at home is $3\text{ meters}$ (about $10\text{ feet}$) away from their TV, which receives a signal which has traveled at the speed of light across the country for $5{,}000 \text{ kilometers}$.
