Quibi

A mobile-first subscription video service built around episodes short enough to watch while waiting in line, launched in April 2020 at the precise historical moment people stopped waiting in lines. Six months later, Quibi announced it would shut down and sell its assets. Roughly $1.75 billion had been raised to teach the phone how to have commercial breaks.
