Can you really see that happening though? The negative associations attached to insect eating are too great. I think it would take more than marketing to change such social norms.
I'm part of the paleo community. I'd love to try eating bugs, and I think most of the people I know in the community would agree.
It could then spread out from that and similar groups. This has already happened with such things as eating offal, which is experiencing a resurgence among paleo groups (and probably foodies, but i'm not one).
I can definitely see, with time, other places "adapting".
