Martina Navratilova used to market this card since ’95, but in 2005 sued sponsor Do Tell, as she was “at odds with the card’s marketing, which she called ‘inappropriate and repugnant.’” She objected to the card being associated with cable shows “The L Word” and “Queer as Folk,” calling the shows “depraved.”
Interesting is that the card was co-branded with Subara, another brand that had Martina as spokesperson.
