Other Top 100 lists
The Top 100 Research Foundation produces more publications about the IT industry than just the IT Services Top 100; since 2003, the Foundation also publishes the Software Top 100, and more recently, the Hardware Top 100.

Software Top 100
The Software Top 100 is a list of the world's largest software companies, ranked by annual software revenues. It is a standard by which software companies measure their relative performance, and it assists software customers looking for successful software suppliers. The Software Top 100 is available at: www.softwaretop100.org.

Hardware Top 100
The Hardware Top 100 is a list of the world's largest hardware companies, ranked by annual hardware revenues. The list includes makers of computer- and communications hardware. It is the first free online overview of the worldwide hardware industry. It is updated annually. The Hardware Top 100 is available at: www.hardwaretop100.org.
