These types of promotions seem to be doing pretty well. The promotion the weather channel ran a few months back broke all records for their website. They had more than a 35% bump in traffic and over 700,000 entries for their contest.
Douglas at BlackBerryCool spotted a promotion that RIM & Ford are offering where you have a chance to win a new 2009 Lincoln MKS or one of 10 BlackBerrys. No word on what BlackBerrys are for the winning but it cant hurt to spin the wheel and see if you win.
