News TV and News website , both are News /Journalism .
If you are leaving News TV and joining News website , these are competing business , only difference being one is broadcasting via TV and other via web. But both are in the field of broadcasting news/News Journalism.
Hence this clause is applicable on you.
Non-compete clause are usually found in most of the employment contracts to protect the businesses /technical know-how/insider information , when an employee leaves the employment.
There is no way around these non-compete clause, if you ignore the clause, your employer can only stop you taking a new job by taking you to court . your employer can also ask for damages and legal cost from you if the matter goes to the court and your employer is proven right .
You can challenge the restrictive clause only if it is unreasonable. Your current employer can not stop you taking a new job unless it could lose them money/damage their business.
Only If a restriction would stop you getting a job that didn’t affect your old employer, then it might not be reasonable and would not be enforceable.
