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
