WestJet partnered with Virool to find out which version of its “Christmas Miracle: Spirit of Giving” video had a greater emotional impact.
For four weeks, Virool ran a short version and long version on eIQ where 1,800 people tuned in to watch and have their emotions read.
In the end, the long version of WestJet "Christmas Miracle: Spirit of Giving" drove two times the emotional impact than the short version.
