Smith Micro Software, Inc., founded in 1982 by William W. Smith, Jr., is a diversified developer and marketer of both enterprise and consumer-level software and services. Though headquartered in Aliso Viejo, California, Smith Micro maintains multiple domestic and international offices, with United States locations in Mountain View and Santa Cruz, California, Chicago, Illinois, and Pittsburgh, Pennsylvania, as well as international locations in Europe and Asia. Recently, the company has shifted focus toward network connection and security technologies, and begun forays into the evolving wireless media industry, as indicated by partnerships with cellular service providers such as Verizon Wireless, AT&T, and Sprint Nextel. Smith Micro initially focused on dial-up modem and fax software technology, distributing predominantly to OEM computer software/hardware manufacturers. With an IPO in 1995, Smith Micro became publicly traded in the NASDAQ under the symbol SMSI. Initial stock offering values were approx. $12.75 per share. By the late '90s, dial-up internet access was being replaced by cable internet, DSL, and wireless broadband technologies due to their substantially higher speed and reliability. This change led Smith Micro to re-apply its network connection expertise to new, wireless and mobile network software. Network connection management became a specialization of the company and, as such, Smith Micro developed products of interest to large-scale mobile network operators such as AT&T, Bell Canada, Orange, Sprint, T-Mobile, Verizon, and Vodafone. While fax and modem-related products were still being sold, the QuickLink family of wireless connection manager became the companys primary source of revenue in the early 2000s.
