The technologies that mass media use keep changing and so a lot of money is spent on getting the latest technology. The TV studio in which the newsreader sits has lights, cameras, sound recorders, transmission satellites, etc. All of these cost a lot of money. One thing more, it is not only the newsreader who needs to be paid but also a number of other people who help put the broadcast together. Due to these costs, mass media needs a great deal of money to do its various works. As a result, most television channels and newspapers are part of big business houses.
