2004 was when the LotR license was still selling and the ML line had finally met up with demand, as waves before 7 and 8 were pretty hard to find. They started expanding the ML toyline this year and creating multi-packs, as the line had become very popular. By 2005 they started making BAFs and a 1:18 line.
Marvel's revenue was exploding during the Marvel Legend years, doubling in just two years.
That Sinister Six box set you're talking about was actually done in 2004. There was a Fearsome Foes box set in 2005. The box sets were selling so well that they even started doing obscure shit in 2006, like Monsters with Dracula and Werewolf. Two packs were also being produced during 2006 and exclusive waves were being planned out too.
