In journalism, yellow journalism is a pejorative reference given to various practices or tendencies of news media organizations which, by the standards of journalistic professionalism, are considered to be unprofessional and detrimental to the principles of journalistic integrity as a whole. The term typically refers to sensationalism in news reporting that bears only a superficial resemblance to the profession of journalism. The term "infotainment" was coined to refer to news programming that blends journalism and entertainment in a way which, critics argue, diminishes the news value and professionalism of the reporting.
