Mass media
1. The mass media are diversified media technologies that are intended to reach a large audience by mass communication. The technologies through which this communication takes place are various. Broadcast media such as radio, recorded music, film and television transmit their information electronically. Print media use a physical object such as a newspaper, book, pamphlet or comics, to distribute their information.
2. Outdoor media is a form of mass media that comprises billboards, signs or placards placed inside and outside of commercial buildings, sports stadiums, shops and buses. Other outdoor media include flying billboards (signs in tow of airplanes), blimps, and skywriting. The digital media comprise both Internet and mobile mass communication. Internet media provide many mass media services, such as email, websites, blogs, and internet based radio and television.
3. While a telephone is a two way communication device, mass media refer to medium which can communicate a message to a large group, often simultaneously. However, modern cell phones are no longer a single use device. Most cell phones are equipped with internet access and capable of connecting to the web which itself is a mass medium. A question arises of whether this makes cell phones a mass medium or simply a device used to access a mass medium (the Internet).
