Clarendon Foundation, Inc. is a tax exempt nonprofit corporation that was organized in March, 1991 as a public interest law firm in the Commonwealth of Virginia.

In September 1991, the Foundation added a new nonprofit activity of providing free instructional television service to accredited educational institutions. The FCC has granted licenses for educational broadcast services in 21 markets across the United States.

Clarendon offered programming about American history and government to schools and colleges. The Foundation branded its public interest television service as "The History Channel."

In 1993, Clarendon assigned its History Channel trademark to the Arts & Entertainment Networks, and rebranded its instructional television services as "TV America."

TV America is being provisioned as an online high definition video service. It is initially offering video on demand programming. With the migration of the World Wide Web to the new Internet Protocol version 6 (IPv6), TV America will be able to deliver live or recorded HD programming with "multicast" routing of its transmissions.

In 2005, the FCC changed is regulations that had initially been adopted to support television transmissions to a new flexible band plan that can be used for analog or digital, one-way or two-way, low-power and high-power signals.

Clarendon has developed relationships with wireless operators, Clearwire, Xanadoo, and other wireless operators to lease spectrum to be used in deploying broadband wireless Internet access networks across the United States. The new networks are using mobile WiMAX, a 4th Generation technology that was developed by Intel Corporation.

In 2007, the Foundation moved its offices to Las Vegas, Nevada, which is its largest market. Clarendon has leased the excess airtime on its EBS license there to Clearwire Corporation. In the summer of 2009, Clearwire launched its Clear Mobile WiMAX service in Vegas.
