Adult entertainment company, Vivid Entertainment has formed a marketing alliance with Collider.com, that will let football fans match wits against Vivid’s “Vivid girls.” It is the first in an anticipated series of promotional ventures between the two firms. In the initial contest, a Vivid girl will post her picks to win pro football games on the Collider.com website each week. Visitors to the site can post their own picks by e-mailing them to Collider. Based on the outcome of the weekend’s games, one winner will be chosen at random from all those who beat the Vivid girl and picks the most winners against the spread. Prizes will include Vivid DVDs, posters of the Vivid girls, hats, t-shirts, and other Vivid branded merchandise.
