O2 had found great success in creating the O2 Arena and O2 Music Academies but wanted to do more with their Priority offering than just offering customers tickets to gigs. So we decided on the brief of making every customer feel like they were O2's priority every day. Priority Moments was born and to this day, remains in the top 20 free apps on iTunes - rewarding millions of O2 customers up and down the country every day.
