consumers use 6 more than 70% of many SM to purchase different products and
services, to provide rich information about certain product and to share
comments with other consumers (Miller and Lammas, 2010). Face book has more
than 6 million consumers who registered to buy and share information about products

able to recommend a product or service to their friends after following that
brand on SM (Parson, 2013). Facebook has reached 51% of users who buy different
products through it (Kunkel, 2013). Twitter has recorded 800,000 followers who
showed their appreciation to the provided services about the products. The same
study has indicated that written blogs has increased from 54% to 77% in two years,
and watching several videos related to different products has increased from
32% in 2006 to 83% in 2008 (Miller and Lammas, 2010). Another study indicated

service to their friends after following that brand on SM (Parson, 2013). Also,
64% of users use Twitter to buy different products (Kunkel, 2013). Instagram is
spreading widely in the recent two years because of active users who share and
upload different kind of photos. Based on the activities provided by users who
use Instagram, the results showed more than 16 billion photos were shared among
users (Krieger, 2012). Phil Gonzalez, the founder of Instagrammers (Instagram
users) was interviewed to recognize the increasing of Instagram users. He
stated in the interview that number of users who login into Instagram increased
in less than two years to 100 million users in more than 60 countries around
the world. (Gonzalez, 2013). Because of the new adoption of Instagram, there is
a lack of information about the use of Instagram as a tool in online purchasing.
