You must have heared of SCO. They own Linux, and every Linux user now owes them money, which is lucky for them as they don't seem to be making much of the stuff right now.
SCO pulled in $8.9m during the first quarter - a major drop from the $11.4m reported in the same period one year earlier. It attributed the biggest chunk of this revenue loss to vanishing Unix product and services sales. On the plus side, SCO managed to trim its net loss to 17 cents per share - one penny better than the 18 cent per share loss reported last year.
