Django: adding multiple values to a model's field

I am new to Django. I am trying to create an app with news, and the companies mentioned in those news, and have created the following models:

class Company(models.Model):
    company_name = models.CharField(max_length=100)
    company_country = models.CharField(max_length=50)

    def __str__(self):
        return self.orgn_name 



class News(models.Model):
    news_title = models.CharField(max_length=200)
    news_link = models.CharField(max_length=100)
    news_date = models.DateField()
    news_company = models.ManyToManyField(Company)  

    def __str__(self):
        return self.news_title

Now, a news might have mention of more than one company. How do I account for that, and enter the list of companies in the database entry? I am using the default Sqlite DB right now.

E.g. a news can be "Facebook competes with Google in AI space" This news has two companies: Facebook and Google.

1) How do I design my models so that they take multiple values for Company?

2) How do I save those values via shell?

3) How do I query it, so that a query similar to SELECT COUNT (DISTINCT 'Company').... should output Facebook and Google separately, and not as "Facebook, Google"?

I am stuck here and desperately need some guidance. TIA
