Sports journalism is a form of writing that reports on sports issues and games. Sports journalism began in the early 19th century when it targeted society's elite and became an integral part of the news business, with newspapers having their own sports sections. The growing popularity of sports among the lower and middle classes has led to an increase in the coverage of sports content in publications. The appetite for sports has led to sports-only outlets such as Sports Illustrated, SportsOpinion.org, and ESPN. Sports journalism comes in many different forms, from play-by-play and game recaps to analysis and investigative journalism of major developments in the sport. The age of technology and the internet has dramatically changed sports journalism as it faces the same problems as the wider print journalism industry, largely unable to recover from costs due to declining subscriptions. In the current millennium, new forms of Internet blogging and Twitter have pushed the boundaries of sports journalism.
