Mass Communication

Thanks for the A2A. I will try to answer the question to the best of my knowledge.
The main difference between getting a MBA in communication management and doing a degree in mass communication and journalism is what you will be doing after getting these degrees.
If you take upmass communication and journalism, you are responsible for creating content. You learn how to create content, how you can look at different ways to structure content, figure out your individual style and learn to extend the boundaries of your creativity.
If you do a MBA in communication Management, you will be managing content. You form the linkage between the creative team and the product expected for your firm. This is a more management-oriented kind of job.
For example, if you are approaching an ad agency for creating your ad for your firm, you would be responsible for giving a brief of what the ad should project the attributes of your product. You specify the target audience and the style of this ad.
The ad agency takes your inputs, analyses your brief and their creative team design an ad for your campaign. You would judge their content, decide if there have to be changes and so on. You would also be responsible for targeting , revenue allocation such as what is your spending for the different modes of communication- how much are you going to spend to air this ad on TV, how much on social media, etc.
One more distinction is that the MBA grad on average would be earning more than the creative team who are the actual brains behind the ad.

Media and cultural courses is a very new field unlike theoretic studies it is more about practical. Media studies is all about how every aspect of media is becoming us so much reliable on them, how it has become a necessity?. Media studies give a detailed study of every sort of media starting from print, radio, television or social media. It also deals with advertisements and public relation and photography as well. One gets to learn every bit of media in a practical way. On the other hand cultural studies is all about the effects of media on the culture and making it enriching. I think one should definitely give a shot as this field is way more appealing and happening than other fields.
