> Times staff pitched story ideas to Dell. One of Dell's first paid posts delves into the topic of millennials in the workplace. The author is a freelancer that the Times contracted, according to Ms. Losee. The millennial generation is among four topics Dell customers are interested in learning more about, she said.

Dell approved the story ideas, which the Times farmed out to freelancers.
