We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
Click on the main gate, then select advertising. Choose you're desired advert type and research it if your level is high enough. Once it's researched you can then select the intensity of your advert campaign by clocking on the chosen advert type.
Regarding the advertising research on the research tree, just click on your main gate and then on research. Advertising is the top one. All it will do is give you an increase in guest numbers.
