Social Group

In my opinion, 'social group' can be define as two or more humans interact with each other, sharing the same opinion and ideas, and having the same status and lifestyle. A group is defined in terms of those who identify themselves as the members of the group.

From my research and readings, there are too many social group to list down. These are some examples I found from the internet.   

Peer group
A peer group is a group with members of approximately the same age, social status, and interests. Generally, people are relatively equal in terms of power when they interact with peers. 
Clique
A group of people that have many of the same interests & commonly found in a High School/College setting; most of the time they have a name & rules for themselves. 
Club
A club is a group, which usually requires one to apply to become a member. Such clubs may be dedicated to particular activities: sporting clubs, for example. 
Household
All individuals who live in the same home. anglophone culture may include various models of household, including the family, blended families, share housing, and group homes. 
Community
A community is a group of people with a commonality or sometimes a complex net of overlapping commonalities, often–but not always–in proximity with one another with some degree of continuity over time. 
Franchise
An organization which runs several instances of a business in many locations. 
Gang
A gang is usually an urban group that gathers in a particular area. It is a group of people that often hang around each other. They can be like some clubs, but much less formal. They are usually known in many countries to cause social unrest and also have negative influence on the members and may be a target for the law enforcers in case of any social vices 
Mob
A mob is usually a group of people that has taken the law into their own hands. Mobs are usually groups which gather temporarily for a particular reason. 
Posse
A posse was originally found in English common law. It is generally obsolete, and survives only in America, where it is the law enforcement equivalent of summoning the militia for military purposes. However, it can also refer to a street group. 
Squad
This is usually a small group, of around 3 to 15 people, who work as a team to accomplish their goals. 
Dyad
This is a social group with two members. Social interaction in a dyad is typically more intense than in larger groups because neither member shares the other's attention with anyone else. 
Triad
This is a social group with three members, which contains three relationships, each uniting two of the three people. A triad is more stable than a dyad because one member can act as a mediator should the relationship between the other two become strained. 
Team
similar to a squad, though a team may contain many more members. A team works in a similar way to a squad. 
In-group
It is a social group toward which a member feels respect and loyalty. It is a group that an individual identifies in positive direction. If a person is part of the in-group then they are collectively part of an inner circle of friends. An inner circle may contain sub-groups within the inner circle including the apex (best friends), core (very close friends), outer rim, etc. This group provides a support structure and being exclusive offers protection from anyone in an Out-group (see below.) 
Out-group
It is a social group toward which a person feels a sense of competition or opposition.It is a group that an individual identifies in negative direction.

The Media

 (1)

Television (TV) is a telecommunication medium for transmitting and receiving moving images that can be monochrome (black-and-white) or colored, with or without accompanying sound. "Television" may also refer specifically to a television set, television programming, or television transmission.

 (2)

Radio is the wireless transmission of signals through free space by electromagnetic radiation of a frequency significantly below that of visible light, in the radio frequency range, from about 30 kHz to 300 GHz. These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.

(3)

A poster is any piece of printed paper designed to be attached to a wall or vertical surface. Typically posters include both textual and graphic elements, although a poster may be either wholly graphical or wholly text. Posters are designed to be both eye-catching and informative. Posters may be used for many purposes. They are a frequent tool of advertisers (particularly of events, musicians and films), propagandists, protestors and other groups trying to communicate a message. Posters are also used for reproductions of artwork, particularly famous works, and are generally low-cost compared to original artwork.

A computer is a general purpose device that can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.

 (5)

A newspaper is a scheduled publication containing news of current events, informative articles, diverse features, editorials, and advertising. It usually is printed on relatively inexpensive, low-grade paper such as newsprint. By 2007, there were 6,580 daily newspapers in the world selling 395 million copies a day. The worldwide recession of 2008, combined with the rapid growth of web-based alternatives, caused a serious decline in advertising and circulation, as many papers closed or sharply retrenched operations.

 (6)

A camera is a device that records images that can be stored directly, transmitted to another location, or both. These images may be still photographs or moving images such as videos or movies. The term camera comes from the word camera obscura (Latin for "dark chamber"), an early mechanism for projecting images. The modern camera evolved from the camera obscura.

The telephone, or phone, is a telecommunications device that transmits and receives sounds, usually the human voice. Telephones are a point-to-point communication system whose most basic function is to allow two people separated by large distances to talk to each other. Developed in the mid-1870s by Alexander Graham Bell and others, the telephone has long been considered indispensable to businesses, households and governments, is now one of the most common appliances in the developed world. The word "telephone" has been adapted to many languages and is now recognized around the world.

Painting is the practice of applying paint, pigment, color or other medium to a surface (support base). The medium is commonly applied to the base with a brush but other implements, such as knives, sponges, and airbrushes, can be used. In art, the term painting describes both the act and the result of the action. However, painting is also used outside of art as a common trade among craftsmen and builders. Paintings may have for their support such surfaces as walls, paper, canvas, wood, glass, lacquer, clay, leaf, copper or concrete, and may incorporate multiple other materials including sand, clay, paper, gold leaf as well as objects.

 (9)
A photograph or photo is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic image such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating photographs is called photography.

A brochure (also referred to as a pamphlet) is a type of leaflet. Brochures are advertising pieces mainly used to introduce a company or organization, and inform about products and/or services to a target audience. Brochures are distributed by mail, handed personally or placed in brochure racks.
