I would suspect you need to have some worthwhile news to provide. Then you would need to contact google news on their specific homepage. If they deem you worthy, then you get added. I may be wrong. Any one else know anything?
Not only provide worthwhile news but also be a company, not only 1 person. I provide entertainment and event news in my country. I would benefit a lot by being inserted into Google News, but they reject because the site is run by 1 person.
