Global vs route specific marketing companies

[Ligo]

I copied my question from Beginners world forum. Anyway, I play in real simulation right now.

I launched a global marketing company in my base country including everything (even TV). Should I create a route specific marketing for both destinations then?
Another words, will the scheme:
A(Base country global marketing) - B (route specific marketing)
work the same as:
A(Base country global marketing + route specific marketing) - B (route specific marketing)
And in the last case I just burn my money?
In my opinion there is no reason to make two companies in my base country where people see the logo of my company on TV everyday anyway:)

I found on practice, that route popularity grows differently if route is one way advertized.

General Marketing affects you Company Image.  You can look up the figure under Office menu.

This variable has a small effect on all your flights to all of the destinations.  As far as marketing, the geographic choices are generally meaningless.  It does not matter what geography you choose to advertise.  How much is spent matters more. 

Route Marketing affects only a specific destination, builds up Route Image.  You can look those up as well under Office Menu.

These are one per destination (and another for trip back).  Route Image goes up on its own as you fly the route.  You can spend money to make it grow faster.  Route Image is very important variable, affecting how many passengers you get on the route.

In general, Company Image and Route Image are completely independent variables, but they both combined have effect on your LFs (load factors).
