How much data do you get with U.S. Cellular’s latest offer? Enough to watch the grass grow — for hours and hours and hours.

We released a seven hours long pre-roll ad. It was a first for the advertising industry. But more importantly, it was entertaining, too.

This ad did more than clearly demonstrate the amount of data U.S. Cellular gives you. This ad did more than win industry recognition. This ad actually developed a cult following of its own. Once people found out about it, they sat and watched all seven hours. They combed through it. They noted and debated their favorite moments in online comment sections. And ultimately, they gave U.S. Cellular more viewing time than we could ever hope for.
