Demand Media

Explaining complicated subjects clearly

Demand Media pioneered search-driven publishing by generating article titles from specific, commonly searched queries. These articles featured on sites including Salon, Livestrong and eHow. Copyright in the articles remains with the original publisher or its successors. I retain archived copies of the original manuscripts and the sources used in preparing them.

Many of the original articles are no longer available online, but a small selection has been preserved at Sciencing.
