Revenue at oci , which helps video rental companies manage sales and inventory , topped out at about $ 2 million , per year in the mid-1990s , but has petered out with that industry , mr. stewart says .

After thousands of children were sickened by melamine-contaminated milk last year , oci helped their parents press for compensation , upstaging a government-backed compensation scheme which offered lower amounts .
