Magazines have a long history dating back to the 1700s in Britain and faced many challenges establishing in the US due to lack of infrastructure. Their growth exploded in the late 1800s due to increased literacy, postal reforms, railroads, falling prices, and more leisure time. Women's magazines in particular saw great success. By the mid-1900s, magazines had become America's dominant mass medium and advertising platform but began declining with the rise of television in the postwar era. Today, magazines face new challenges from digital media but some have found online success through websites like Slate and Salon.
