First Space Product ???

Joe beat me to tourism, so I'll go with entertainment.

A dance company, say a half-dozen people. Not only do they put
out their own product, but they can be hired. Say a band wants
a bit of zero-G dance in their next music video. Well it would
be too expensive to send the band into orbit AND teach them to
dance(*) AND have them away from the touring circuit. So they
hire the Stardancers(**) to come up with that dance to their
latest song, the imagery is sent down, the band records their
part on the ground and the editing is also done on Earth.

Ultimate Fighting championship... IN ORBIT! Pay-per-view.
Three-D ball games.
Weightless gymnastics.

Of course, Joe's tourists can watch these event live and in
person... for an additional price.

Oh, and how about getting Jackie Chan into weightlessness
before he dies or retires? Being able to market an action
film with "Jackie Chan Does All His Own Stunts... IN SPACE!!"
would sell a lot of tickets.
