We Muslims should establish institutions and programs according to our values and principles, we should not imitate and follow others especially when this leads to things and actions that are prohibited. I want to become a journalist, but my parents say that I have to be a doctor when I grow up. Parents' responsibility is to see that whatever their children do is permissible in Islam and they do it with serious commitment. According to Islam, you have every right to choose your own career. You should do what you feel you can do best.
Journalism is a very important profession and it is very much needed.
We need very good Muslim journalists who can present Islamic viewpoints in a professional manner. Talk to your parents nicely and try to convince them that you can do well as a journalist also. If they need to discuss this matter further, take them to some counselors who can help them understand that journalism could also be a good and successful profession. I wish you all the best.
