Mass Communication

First things first, I would like to applaud you for the fact that you have realized your "real" core interest and want to pursue it as a career. This is a brave thought and requires real care, focus and planning. I would suggest you should take a pause, think and then act so that you have enough time, information and facts before you make any decision.
Next, how to go about it? We need to keep a few fundamental things in mind while we think, plan and act on such a career change move. Here are some tips:
1. Even if you are well off financially, first identify the source of your bread and butter. I believe, for you it is your medical profession. So continue to work hard in this domain. Do not blink.
2. You can approach it in two ways: (a) First become a host of any show and then move into travel specific profile; Get into travel industry and then move on to become a host.
2. In order to achieve this in an organized manner: Create a project plan with specific dates and goals. This has to be a research project where you will find out the career options in the "Travel" industry and specifically the opportunities to be "Host" of a "Travel Show". You will need to dig information from all possible sources. By the way, you are already doing it by asking this question on Quora. So continue to dig information from all possible sources, viz, Internet, Friends, Acquaintance, Books, Newspapers etc. Please note you need to execute it as a time bound project.
3. Once your research project is over(within the timelines originally set), the logical next step is to ponder over the outcome and find out the "real" and "viable" options that you can pursue. The result may give you range of opportunities. You may want to first get into the travel industry in the best profile "available" and then look for being a "host" OR you may first opt to become a "host" and then look for hosting profile in travel domain.
4. As mentioned in Step 1, while doing this research you are still continuing your medical profession so whatever research you do is going to be an additional effort on top of your day to day job. This is going to test your patience, energy level and passion for changing to a new career stream.

The GGSIP University is one of the first few institutions in the NCR to have launched Masters programme both regular and weekend- during the last six years. Earlier known as the Master of Mass Media (MMM), now the regular programme has been rechristened as the Master in Mass Communication (MMC) that offers the following specializations in the last two semesters: (I) Journalism and News Media, (ii) New Media & Convergence, (iii) Corporate Communication and (iv) TV Production. The School plans to have the flollowing specialization in near future (I) Broadcast Journalism, (ii) Print Journalism, (iii) Online Journalism, (iv) Advertising & Corporate Communication and (v) TV Production.
The programme aims at helping a student evolve into a professional who is capable of meeting not only the current needs of the industry but also what the industry and society would need in future in view of the dynamic local and global environments. Having given an overview of the industry and its professions and also trained into basic content and technical skills, she is required to do Case Method studies to have a hands-on experience in the domain of her choice and finally come out with a substantial research work on the given subject.
