G.I. JoeAmazon and Hasbro have signed a licensing agreement that will allow independent writers to publish G.I. Joe stories through the Kindle Worlds program. The arrangement coincides with the action figure’s 50th anniversary.

G.I. Joe was first put on display at the 1964 New York Toy Fair and entered the retail market before the holiday season later that year.

Among a number of other Kindle Worlds licenses announced at the same time was Veronica Mars.
