History

8×8 was founded in 1987 by Dr. Chi-Shin Wang and Dr. Y.W. Sing formerly of Weitek as Integrated Information Technology, Inc., or IIT. The name was changed in the early 1990s. They began IIT as a fabless vendor of semiconductor products for the math coprocessor and graphics chipset markets. The company produced x87 floating point coprocessor for the 286, 386 and 486 generations of microprocessors as well as graphics accelerator chips for the personal computer market during the late 1980s and early 1990s.

In 1992 the company began shipping a lossless data compression product called Xtradrive. In the early 1990s IIT began producing chips, software and other technologies for the videoconferencing market. The company changed its name to 8×8 and began marketing its own set-top videoconferencing systems for consumers under the ViaTV brand. 8×8 went public on the NASDAQ market in 1997, trading under the ticker symbol EGHT.

In January 1999, 8×8 launched a family of Voice over IP (VoIP) chips and software that were sold to IP phone, IP/PSTN gateway and other manufacturers of VoIP equipment. 8×8 acquired two companies (Odisei and U|Force), to acquire network/server VoIP technologies, and began selling an end-to-end VoIP services technology solution to service providers in 1999.

In 2002, the company relaunched itself as a VoIP service provider under the Packet8 brand. In 2003, it launched its first consumer videophone services on the Packet8 network. In 2004, the company became the first VoIP service provider to offer replacement, E-911 services to its subscribers.[8] It also launched a suite of business services called Packet8 Virtual Office. In July 2007, 8×8 “entered an agreement … to accept” the 200,000 customers who abruptly lost phone service when VoIP startup SunRocket was liquidated. At the time, the Washington Post described Packet8 as “the third-largest independent Internet-phone service provider with 181,000 customers.”

On 25 July 2002, 8×8 announced that its application for listing on the Nasdaq SmallCap Market had been approved. 8×8 retained its ticker symbol of EGHT, and began trading on the Nasdaq SmallCap Market on Friday, 26 July 2002.

On September 1, 2004, the company began selling their product at Fry’s stores. 8×8 finished a series of TV commercials featuring San Francisco 49ers players. In 2009, 8×8 added Unified Communications to their portfolio and a contact center solution and mobile solutions in 2011.

8×8 has been awarded 128 patents related to semiconductors, computer architecture, video processing algorithms, videophones and communications technologies and security. In October 2014, 8×8 reported a customer base of more than 40,434 businesses.
