We invited every one involved involved with U2 VENI’s and the coolest night club’s facebook groups to the U2 VENI EFERVESCENT CALL.7,000 balloons inflated with helium, representing the voice of 7 millions salvadorians where released to the sky through a removable roof to experiment an efervescent effect while everyone was screaming U2 COME HERE.We filmed the activity and uploaded a video to the same sites so people could see the brand activation and made a special copy to be delivered to U2

1,125 people attended the activity.The activity reinforced the national campaign, the product’s benefits and its attributes.60,000 people (6% of the total internet users in El Salvador) were exposed to the brand activation in the U2 VENI campaign sites.U2 VENI facebook group and www.u2veni.org grew 8% one week after the event as members of the night club’s facebook group became fans.The efervescent call was received by U2.
