For Media dominance's determination method suggested above, perhaps you could give an example to illustrate the method more clearly.
So let's begin:
First, we got 5 media companies - 2 tv, 2 radio, 1 newspaper.
The city's population is 1,000,000 people.
The ratings are, as follows:
TV1 - 45% /3 $ per ad/
TV2 - 20% /3$ per ad/
Radio1 - 60% /4$ per ad/
Radio2 - 25% /4$ per ad/
Paper - 50% /2$ per ad/
So let's say Corp1 owns TV1 and Radio1, Corp2 owns TV2 and Radio2, and Corp3 owns the newspaper.
Corp1 got 45% and 60% out of 1 mil = 1,050,000 potential people to adv. to
Corp2 got 20% and 25% out of 1 mil = 450,000 potential people to adv. to
Corp3 got 50% out of 1 mil = 500,000 potential people to adv. to
(2,000,000 potential listeners, reader, viewers)
Corp1 got more than Corp2 and Corp3 (not combined), so it's dominant.
is all about media share and potential viewers, listeners, readers
------------------
Or something else:
tv1 makes 3,000,000$ monthly,
tv2 makes 2,000,000$ monthly,
radio1 makes 1,500,000$ montly,
radio2 makes 2,000,000$ montly,
newspaper makes 2,500,000$ montly
Corp1 makes 4,500,000$ montly
Corp2 makes 4,000,000$ montly
Corp3 makes 2,500,000$ montly
so Corp1 is dominant.
Is all about the profits. It also must be adjusted to the sums corp1, corp2 and corp3 pay for "new content and development" montly.
If corp1 pays 400,000$ for new content and corp2 pays 500,000 for new content -->
Corp1 still gets 4,100,000$ and corp2 gets 3,500,000$ montly.
It can be 2 diff dominances - media market share and advertising profits - in these cases, Corp1 has them both.
---------------------
So what about combination of both, as one single dominance form?
I prefer something simple as that:
Corp1 got 4,500,000$ profits this month out of 11,000,000$ montly earnings in the bussiness for all 3 corps. This makes 41% of the market.
Corp1 got 1,050,000 potential people out of 2 mil, this makes 53%. So corp1 got
94 points control of this bussiness combine of potential people to adv to and profits.
Corp2 got 4,000,000$ profits this month out of 11,000,000$ monthly earnings in the bussiness for all 3 corps. This makes 36%
Corp2 got 450,000 potential people out of 2 mil, this makes 23%. So corp2 got
59 points control of this bussiness.
Corp3 got 2,500,000$ profits this month out of 11,000,000$ monthly earnings in the bussines for all 3 corps. This makes 23%
Corp3 got 500,000 potential people out of 2 mil, this makes 25%. So corp3 got
48 points control of this bussiness
So Corp1 is dominant for complete control of media/adv bussiness with 94 points.
