Established in 1952 by two pillars of Houston history, bankers WT Carter and Jesse Jones, Phonoscope has always seen the value of using communications to facilitate economic development and wide community participation. Together they brought in partner technological visionary Lee Cook, the pioneer of two-way video communications, now better known as video conferencing. Under Cook’s innovative guidance, Phonoscope developed and installed the world’s first video conferencing system in the 1950s in its downtown office.
Phonoscope went on to bring broadband to Houston, to support two-way audio and video communications to connect individuals, companies, schools and hospitals. It even supports NASA.
We launched our first Gigabit service in 2006, making Phonoscope a pioneer in high-speed business connectivity. Today, we have grown to be the largest private, metro-area, Gigabit active Ethernet network in Houston, in the nation and in the world.
