Mass media  Mass media refers to a diverse array of media technologies that reach a large audience via mass communication. The technologies through which this communication takes place include a variety of outlets. Broadcast media transmit information electronically via media such as films, radio, recorded music, or television. Digital media comprises both Internet and mobile mass communication. Internet media comprise such services as email, social media sites, websites, and Internet-based radio and television. Many other mass media outlets have an additional presence on the web, by such means as linking to or running TV ads online, or distributing QR Codes in outdoor or print media to direct mobile users to a website. In this way, they can use the easy accessibility and outreach capabilities the Internet affords, as thereby easily broadcast information throughout many different regions of the world simultaneously and cost-efficiently. Outdoor media transmit information via such media as AR advertising; billboards; blimps; flying billboards (signs in tow of airplanes); placards or kiosks placed inside and outside buses, commercial buildings, shops, sports stadiums, subway cars, or trains; signs; or skywriting. Print media transmit information via physical objects, such as books, comics, magazines, newspapers, or pamphlets. Event organizing and public speaking can also be considered forms of mass media. The organizations that control these technologies, such as movie studios, publishing companies, and radio and television stations, are also known as the mass media. In the late 20th century, mass media could be classified into eight mass media industries: books, the Internet, magazines, movies, newspapers, radio, recordings, and television. The explosion of digital communication technology in the late 20th and early 21st centuries made prominent the question: what forms of media should be classified as "mass media"? For example, it is controversial whether to include cell phones, computer games (such as MMORPGs), and video games in the definition. In the 2000s, a classification called the "seven mass media" became popular. In order of introduction, they are:   Each mass medium has its own content types, creative artists, technicians, and business models. For example, the Internet includes blogs, podcasts, web sites, and various other technologies built atop the general distribution network. The sixth and seventh media, Internet and mobile phones, are often referred to collectively as digital media; and the fourth and fifth, radio and TV, as broadcast media. Some argue that video games have developed into a distinct mass form of media. While a telephone is a two-way communication device, mass media communicates to a large group.
