AS it launched its 2015 campaign in the heart of Adelaide on Thursday evening, Port Adelaide also invited its supporters and members to celebrate its club family right around the country through the launch of its 2015 TVC.

Featuring on the Seven Network and Foxtel, and on portadelaidefc.com.au, the Port Adelaide TVC breaks the mould of traditional call-to-arms commercials and instead reflects the nature of the Port Adelaide supporter to the country.

Bold, passionate and resilient, the TVC starts penning a letter to 'All those True Believers...' - the ones who've ridden all the ups and downs of football life with the club over many years and are on-board for the club's next exciting chapter in 2015.

"Port Adelaide is on the cusp of reaching a historic 60,000 members and we hope this TVC explains why that is," says the club's head of membership Matthew Richardson.

"It doesn't sell anything to supporters, but it sells the Port Adelaide supporter to the world.

"We wanted to celebrate the passion of our community and the journey we are on together at Port Adelaide, and we know all our people can't wait to continue that journey in 2015." 

And it ends with a simple message at the end.

But you'll need to watch to find out what that message from the club is...
