Definition of Mass Communication: Mass communication is any form of communication that intentionally reaches a larger, disperse audience. An essential element to remember: it's not an "accident" but "intentional". Imagine a public speech by a mayor to his city residents, or a news bulletin aired on the BBC. They're both meant for large audiences.

Medium and Style in Mass Communication: The medium (how the message is transmitted) impacts the language style used in mass communication. Think of the difference between a formal report presented in a board meeting and the casual tweets from Elon Musk; they are both forms of mass communication but the language and tone differ dramatically based on the medium used.

Not Everyone Can Do Mass Communication: Although we all have the chance to create mass communication, the major part is controlled by mass media and government due to logistics and costs. Setting up a TV station or producing a blockbuster movie isn't cheap, right?

Key Aspects of Mass Communication:

a) It requires formal organization and resources.

b) It is typically aimed at a large audience over a wide geographic area.

c) Mass communication unifies an audience, but extensive interaction among audience members is limited.

d) Mass communication involves the 'reification' of language: it is made concrete, prepared, and can be repeated or redistributed.

Learning about Mass Communication: Understanding mass communication is an exploratory process, learned indirectly through critical exploration of different media and topics.

Medium and Communication Style: Compare a TED Talk (medium: stage presentation) with a YouTube vlog (medium: video sharing platform). Both are examples of mass communication. However, a TED Talk often involves formal language, use of props or presentation slides, and a well-rehearsed delivery. On the other hand, a YouTube vlog could be more casual, spontaneous, and conversational. The chosen medium dictates the style of communication.

Unequal Distribution of Mass Communication: Think about the creators on YouTube versus the viewers. While everyone can upload videos (the opportunity), only a small percentage of creators (think of PewDiePie or MrBeast) hold the majority of the viewership. This highlights that although everyone has the potential to engage in mass communication, the majority is controlled by a minority.
