Câu hỏi: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.
According to a mobiThinking.com report on global mobile statistics, as of February 2013, 96.2 percent of the world's population has a subscription to mobile cellular service. As an average, that means that almost everyone in the world has a mobile phone! Even for the region with the lowest use level in the study, the market saturation is just over 63 percent. In highly developed nations, the saturation is well over 100 percent, meaning that people have more than one mobile phone service.
Even though most of the world's population has mobile service, it doesn't mean that an organization can blast a call or message to everyone, though it might be technically possible. In addition to laws that prohibit this type of communication, phone conversations are still one-to-one (or one-to-few with conference calling) connections.
As well, text messages, even though they can technically be broadcast to millions, cannot legally be sent unless the mobile subscriber opts in to receive. So, in one sense, text message campaigns could be classified as mass media since they are a one-to-many communication. But due to the opt-in nature of these campaigns, the mass that they reach will be limited.
That being said, there is no doubt that mass media communications delivered via mobile devices, particularly through mobile apps and push notifications (alert messages that pop up on a mobile device screen), will become a primary delivery system of the future.
Similarly, email is often a one-to-many communication, particularly for communications such as email marketing and newsletters. Like text messaging and cell phone calls, a person must share an email address (opt-in) in order to receive messages. Broadcasting to the masses without permission violates the Federal Trade Commission's CAN-SPAM Act. As with mobile text messages, email can be a mass media communication but will be limited.
