Magazines have existed since the 17th century, starting as literary and philosophy publications in Germany. The first general interest magazine was published in London in 1731, while the first illustrated magazine launched in 1842. Magazines are distributed through mail subscriptions, sales at retailers, or free pick-up locations. Subscribed magazines fall into paid circulation, non-paid circulation, or controlled circulation categories. While seeming like a simple distraction, magazines have significant impacts on society through influencing body image, transforming political views, and shaping consumer purchasing through advertising.
