The Nasdaq Stock Market, an exchange that typically attracts a high number of technology listings, said on Tuesday that it had launched an index to track the performance of a broad range of companies offering Internet-related services.

The Nasdaq Internet Index is designed to track the performance of companies offering such services as Internet access, Web-based searches, Web hosting, Web site design and Internet-based retail, according to a company statement.

The index is made up of Internet companies that trade on Nasdaq and other U.S. exchanges, Senior Vice President Steven Bloom said.
