A global energy company wanted to champion some of their legacy advertising and re-kindle engagement with their consumer base in an online campaign. We crafted some "trailer-style" teaser videos, with a strong call to action asking the consumer to engage with the legacy material. The result boosted their existing video ranking by sending a torrent of new visitors to old content, creating an upsurge trend. This technique is useful for keeping legacy content alive and capitalising on existing following and SEO. Most of the work was focused in on the audio track, with impactful sound design giving the teaser films a real hollywood film trailer quality.
