RR-soybeans were introduced commercially by Monsanto in 1996. The first
year about 2.5% of U.S. soybean acreage was RR, and that proportion grew
to 15% in 1997. In both years the entire supply of RR soybean seeds was
sold out. Seed availability apparently is the major factor limiting the
market share of RR-soybeans in the U.S. at the moment.
I don't have the numbers handy for cotton, but again the growth in U.S.
market share has been limited by seed supply and not by demand. Likewise
for RR-'Yield Guard'-maize, which was planted on 750K acres in the U.S.
