This campaign is integrated with the weather. The user chooses a city, e.g. Sao Paulo, and if it's raining over there, there will be an ad which promotes the C4 Pallas sensitive wipers and if there's a sunny day in Sao Paulo, the other ad will be displayed, which promotes the C4 Pallas scented air-conditioner. This integration is possible through RSS weather conditions feed. This is the "Rainy Ad".
