Output per hour rose 15.7 percent per year among software publishers. Productivity growth in the telecommunications industries was also strong, with an increase of 9.9 percent per year posted by the wireless telecommunications industry and an increase of 6.2 percent per year registered by the wired telecommunications industry.
The one industry among the seven with a decline in productivity from 1987 to 2001 was cable and other subscription programming.
