In the Equilibrium video, for example, all of the sellers are wearing ties. The ties imply that the sellers are all men. This (a) is not true and (b) makes women feel like they don't belong in business. Although I think that the content of the video is great, I teach at a women's college where my students are likely to protest at including such a stereotyped depiction. (The buyers are all wearing pants, so could be interpreted to be male as well, but since they are not wearing ties they don't look as obviously gendered.)
