message, and (4) a decision whether the forward
message to the other person. Share is an important
measurement in viral marketing success especially
on social networking sites and refers to a level where
users exchange, distribute, and receive content
(Kietzmann et al., 2012). In the form of social
relationships, sharing often involves the exchange of
information between people and content. In some
case, sharing behavior often associated with
relationships between people (Engestrom, 2001).
Some previous studies have examined the factors
that affect the behavior of sharing (passing) viral and
email messages that are commercial (Bruyn and
Lilien, 2008: Dobele et al., 2007: Phelps et al., 2004:
Porter and Golan, 2006). These studies have
identified some important factors that motivate
someone to do pass some messages in writing a
commercial and viral email, namely due to the social
advantages, amusement, and attachment to a friend.
Kramer et al., (2014) conducted a study that
proved the effect of social media against the
emotions of its users. Kramer et al., (2014) found
that when a person is exposed to a lot of social
media content which negatively worded, chances are
he'll post content which negatively worded will also
increase. Conversely, if someone more often
exposed to positive content, post positively worded
content will also grow. However, in reality, much of
the information content presented to the public now
tends to be negative, which contains anxiety,
violence, and moral destruction. This led to growing
number of depressions and the level of aggression in
society (Chaturvedi and Chander, 2010).
In research conducted by Muntinga et al., (2010)
mention that the behavior of the share is one
dimension of engagement along with other
dimensions, namely: likes and comments. But once
again the context used by Muntinga et al., (2011) is
the use of social media in the community of the
brand. In addition, the research of Pirouz et al.,
(2015) has mentioned that the content contains
humor, amazing, and disgusting has been widely
discussed by some of the research. More content
with the concept of the video turned out to be better
able to maximize the influence of emotion headed
into viral (Berger and Milkman, 2011). Content that
contains entertainment, information, and talents, in
touch with the trend or event, help others, expressing
personality, communicate with others, are the main
factors that lead content to be viral (Izawa, 2010).
In contrast to Berger and Milkman (2011),
Thompkins (2012) mentions the term online content
as the characteristics of the message. According to
him, there are three types of factors that led to the
success of viral marketing, namely: the message
characteristics, the message sender or recipient
characteristics, and social networks characteristics.
The research of the Golan and Zaidner (2008)
concludes, that the content is both humor and sex
appeal is the most commonly used tactics in the
message viral, and social visibility of a viral
message will encourage the process of diffusion
(Susarla et al., 2012). An earlier study conducted by
Severn et al., (1990) however in conventional
advertising content describes the effects of sexual
content in the form of communication effectiveness
against controversial advertising messages and its
effects on product and intent buy. The results of his
research concluded that sexual content in advertising
turned out to be preferred on the consumer either
male or female. In addition, the research of Almeida
(2016) stated the influence of the difference in the
types of online content from a social networking site
that is Facebook post behavior on sharing. Content
types include online application, event, fun,
information, pool, promotion and publicity, and
service. More specifically, Petrescu (2012) who
conduct research in conceptual and empirical
evidence on the influence of viral marketing on the
intention to buy, which one is from about advertising
appeals consisting of humor, sexual, and
informative, stating that humor is one of the types of
content are most often in the forward right because
at the humor contained very deep emotions.
Petrescu's argument (2012) this simultaneously
supports research conducted by Phelps et al.,.
(2004).
Motivation has become a research topic in social
media, particularly to explain why someone decided
to join and use social media. On social networking
sites such as Facebook, someone motivated due to
social ties (social connectivity) and communication
with his friend (Barker, 2009). Lin and Lu (2011)
observing that someone motivated to use social
networking sites to benefit self-enjoyment, benefit
from that site, and build a network. People see and
do share YouTube videos, information and funny
content, as motivated by an element of
entertainment, interpersonal expression, seek
information and build relationships (Hanson and
Haridakis, 2008). The motivation for using social
media is also very depending on the domain. In the
context of education, a social media is becoming
very popular in the teen age. Social media is useful
as a tool to improve student learning, searching for
ideas, and learning in the context of relations
between students and teachers (Mazer et al.,, 2007).
But in the work environment, the motivation for
wanting to establish rapport, useful, and a desire to
share personal or professional, is motivation-
motivation informing someone using social media
(DiMicco et al., 2008). But most research is focused
on informing motivation to join in social media.
Still, relatively little research focusing on motivation
