It's been going on for decades. Film chemicals that coat the film and react with the various colors coming through the lens weren't made to cope with a diverse set of skin tones.
Back in the 1940s and 50s, the standard was called a "Shirley card," which was used to calibrate the colors for printing. These checks were based on white skin tones. This is changing with digital photography and its technology, but creating awareness and making it known is another step forward for mankind.
We've fixed a lot of these biases with the digital revolution. Yet, we still have misrepresentation of darker skin tones in magazines and advertisements. These biases have also been brought from the film days to the digital era, as the video mentions. As photographers, the only way to change this is to promote and use the brands that actually make the changes needed to their software and hardware, whether it's sensors or the way the software responds to the sensor's data throughput. As Estelle Caswell says: "Tools are only as good as the people who use them."
I will most certainly pay more attention to skin tones and the way the camera responds to the colors it's taking moving forward. Digital photography can change this. I'm looking forward to a period where people and moments in time are documented with equal and real color renditions. As the video says: "Technology should be the ultimate equalizer to serve everyone's needs without an inherent bias."
