The Detroit News has a long history of using technology advances to the benefit of its readers. The paper launched the nation’s first commercial radio station when it started WWJ radio in the 1920s, and was the first newspaper to operate a television station when it debuted WWJ TV Ch. 4 in 1947. It also was the first newspaper to have an aircraft dedicated to news gathering, and was among the first to publish aerial photographs. In 1995, it was among the first newspapers to go online with a Web site.  Today the newspapers use Atex Advertising to book all classified ads for both on-line and print publications.
