  Social Networking Sites (SNSs) are powerful marketing and communication
tools. There are hundreds of SNSs that have entered and exited the market over
time. The coexistence of multiple SNSs is a rarely observed phenomenon. Most
coexisting SNSs either serve different purposes for its users or have cultural
differences among them. The introduction of a new SNS with a better set of
features can lead to the demise of an existing SNS, as observed in the
transition from Orkut to Facebook. The paper proposes a model for analyzing the
transition of users from one SNS to another, when a new SNS is introduced in
the system. The game theoretic model proposed considers two major factors in
determining the success of a new SNS. The first being time that an old SNS gets
to stabilise. We study whether the time that a SNS like Facebook received to
monopolize its reach had a distinguishable effect. The second factor is the set
of features showcased by the new SNS. The results of the model are also
experimentally verified with data collected by means of a survey.
