Popular Mechanics is a magazine of popular science and
technology, featuring automotive, home, outdoor,
electronics, science, do-it-yourself, and technology
topics. Military topics, aviation and transportation of all 
 types, space, tools and gadgets are commonly featured.

It was founded in 1902 by Henry Haven Windsor, who was
the editor and, as owner of the Popular Mechanics Company,
the publisher.

For decades, the tagline of the monthly magazine was "Written
so you can understand it." In 1958, PM was purchased by the
Hearst Corporation, now Hearst Communications.

In 2013, the US edition changed from twelve to ten issues per
year, and in 2014 the tagline was changed to "How your world
works." The magazine added a podcast in recent years,
including regular features Most Useful Podcast Ever and How
Your World Works.
