It has been a trend for past couple of years that journalism papers are neither set on traditional pattern nor confined to just analysis restricted to conventional print and electronic media jargons, rather they are turning out to be added with some new analytical topics, like Cognitive Dissonance, Communication congruity, Embedded journalism, spinning stories, new trends in mass media sciences after the advent of internet and countless number of satellite channels reachable by common man,,so it is my fraternal advice to all of you to prepare the subject on the basis of ever-changing innovative trends( which is definitely a part of slowly but gradually altering CSS exam pattern)..Follwing topics could be regarded as some prominent cases in point :

Some Communication Theories:
1. Consistency and selective perception
2.Theory of cognitive dissonance
3.Theory of Cultivation
4.Osgood's congruity theory
5.Hypodermic and Hyperdermic theories of communication

I might not be fully exhaustive in mentioning all the topics, its was just an indicative overview,, so participation from you people is also awaited
