hasbro is making also the most off of MLP I believe than any other of their products
Pretty sure they make the most off of Transformers, specifically the live-action movies (abominations that they are, they are massive cash cows).
Totally this. Hasbro continues to make most money out of its boy lines. The impression that people seem to be under that Hasbro make most from MLP is a misreading of the facts. The last couple of years has seen an increase in revenue in the girls line - thanks to both MLP and also the One Direction line that Hasbro create. However that increase [17% in 2012 and 26% in 2013] still only takes revenue to a 1/4 of the companies over all gross revenue.
Despite the boys line declining by 22% in 2013, it still grossed $200 million more than the girls line. And Hasbro's ever popular Games lines took $300 million more than the girls line. Hasbros bread & butter has always been lines like TF, Nerf and GI Joe as well as its staple board games; they make the most from them and unfortunately with the new TF movie coming out and such a sharp decline in the boys line last year, I am sure thats where you will see them focus their attention for a while.
