with Thriller, his international support was greater than it was with Bad, Dangerous, and History
during its initial run, Thriller sold 47 million copies worldwide, selling 25 million in the united states alone, the other 22 million were sold internationally
during Bad's initial run, it sold 25 million copies worldwide, selling 6-8 million copies in America, so that indicates the other 17-19 million copies sold was a couple of million less than Thriller
during DAngerous intial run, it sold 20-22 million copies, selling 6-8 million copies in America, the remaining sells of 14-16 million occured overseas, Thriller sold more
and with History initial run, selling 15 million copies world wide (if you count both discs as a single sale) 4-6 million were sold in america, the remaining 10-15 million were sold over seas, over half less than what he achieved with Thriller
Thriller was not only his greatest selling album in America, but overseas as well, based on that trajectory, as MJ said in his book Moonwalk, he expected to sell 100 million copies worldwide
