Still the Raiders line was up against G.I. Joe, the bain of Star Wars toys at the time. . .
All three were Kenner lines, right?
Technically, GI Joe was Hasbro in the 80s and they hadn't mergered with Kenner yet at that point. In 1984, Hasbro bought Milton Bradley and Playskool to become the largest Toy Company in the USA. They didn't buy Kenner until 1991 when they acquired Tonka who was holding the Kenner brand.
But if yesterday's kids weren't into Indy, why would today's adults be?
I think the biggest reason that the Indy toys did not sell well was Kenner's usual production delay. Similar to when they got a late start on SW stuff, the Indy toys did not hit stores until '82-83, even though Raiders came out in '81.
You can find a lot of history of the original Indy line at the
Official Indy site. It was an interesting article then and it still holds well today. Lots of history and reasons why the first Indy line tanked with kids compared to the SW Stuff. And, just to add some fuel for the debate, it's interesting to see what LFL had to say about indy toys just over a year ago...
"Roffman suggests that should another Indy film be released, a new toy line would definitely be considered. "
I'm not sure it would necessarily be 3.75" action figures, but something that's more in line with what we've done with [Star Wars] Unleashed -- a larger scale, more detailed action figure."
