This strikes me as a very on-point answer. Other people have noted that "Annual Report" and "10-K" aren't precisely the same thing: the 10-K is the annual SEC filing, akin to the 10-Q filed quarterly. The annual report is what's sent to investors. It can just be the 10-K, but I've definitely seen many companies in the past that did what amount to full-color brochures. I'm pretty sure the phone company I worked at in the late 90s had very pretty ones, although not as witty as Netflix's.
