Philco Corporation: A Brief Overview and Historical
Context
Philco
Corporation, also known as the Philadelphia Storage Battery Company, was a prominent
American consumer electronics company that specialized in the production of radios
and televisions. It was founded in Philadelphia in 1892 as the Helios Electric Company
and later changed its name to the Philadelphia Storage Battery Company in 1906.
During the early years, Philco primarily manufactured storage batteries for various
applications, including electric vehicles and radio receivers. However, it wasn't
until the 1920s that the company began producing radios under the Philco brand name.
Philco quickly gained popularity for its innovative designs and reliable performance,
becoming one of the leading radio manufacturers in the United States.
In the 1940s, Philco expanded into television production, capitalizing on the
growing demand for this emerging technology. The company introduced a range of television
sets, including black-and-white models and later color televisions. Philco's televisions
were known for their quality construction and advanced features, and the brand became
a trusted name in the industry.
1945, Philco Corporation owned and operated WPTZ, a television station located
in Philadelphia. WPTZ, which was originally licensed as W3XE, was one of the pioneering
television stations in the United States. It began broadcasting experimental television
programs in the 1930s. Philco Corporation, being a major player in the consumer
electronics industry, recognized the potential of television and acquired the station
in 1941. The acquisition allowed Philco to have a direct stake in the emerging television
market.
Under Philco's ownership, WPTZ expanded its operations and became a fully licensed
commercial television station. The call letters were changed to WPTZ, standing for
"Philco Television Station, Philadelphia." The station continued to broadcast a
variety of programming, including news, sports, and entertainment content.
Over the years, Philco continued to innovate and introduce new technologies.
In the 1950s, they introduced the Predicta line of televisions, featuring distinctive
designs with swivel screens and futuristic styling. However, despite its success,
Philco faced increasing competition from other consumer electronics manufacturers,
and the company began to decline in the 1960s.
Philco went through various ownership changes and financial struggles in the
following decades. The original Philco Corporation went bankrupt in 1960, and the
brand changed hands several times. Today, the Philco name is no longer actively
used in the consumer electronics market.

Radio Corporation of America (RCA)
The
Radio Corporation of America (RCA) was founded in 1919 as a subsidiary of
General Electric (GE), but became an independent company in 1929 when GE was
required to divest itself of RCA by the U.S. government due to antitrust
concerns. RCA
quickly became a dominant player in the
radio and electronics industry. Its early success was due in part to the
fact that it held key patents on radio technology.
One of RCA's major contributions to the electronics industry was the
development of the first commercially successful radio broadcasting system in
the United States in the 1920s. RCA also played a major role in the development
of emerging television technology, and was instrumental in the introduction of
color television in 1954.
RCA's early years were marked by a series of high-profile achievements,
including the first transatlantic radio broadcast in 1922 and the introduction
of the first commercial radio network, the National Broadcasting Company (NBC),
in 1926.
RCA also played a major role in the development of the phonograph and record
industry. In the 1950s and 1960s, RCA's record label, RCA Victor, was one of the
largest and most successful in the world.
During World War II, RCA played a critical role in developing radio and radar
communications systems and was a major supplier of electronic equipment to the
U.S. military. After the war, the company focused on expanding its consumer
electronics business. After the war, RCA continued to innovate in the
electronics industry, developing technologies such as the first liquid crystal
displays (LCDs) and the first digital video recorders (DVRs).
In the 1980s, RCA was acquired by General Electric, and its operations were
gradually integrated into GE's other electronics businesses. Today, the RCA
brand is still used on a variety of consumer electronics products, but the
original company no longer exists as an independent entity.
Despite its early success, RCA began to struggle in the 1970s. The company
was slow to embrace new technologies like digital audio and video, and it faced
increased competition from Japanese electronics companies.
In 1986, RCA was acquired by General Electric (GE) in a deal worth $6.28
billion. GE spun off RCA's consumer electronics division in 1987, and the
company's remaining assets were folded into GE's other businesses.

Westinghouse Electric Corporation
George Westinghouse (1846-1914) was an American entrepreneur and inventor who
played a significant role in the development of the electrical industry. In 1886,
he founded Westinghouse Electric & Manufacturing (later changed to Westinghouse
Electric Corporation), initially focusing on electrical equipment, including transformers
and generators.
In the late 19th century, there was a debate over whether direct current (DC)
or alternating current (AC) should be the standard for electrical power distribution.
Thomas Edison championed DC, while Westinghouse and
Nikola Tesla, a Serbian-American
inventor and engineer, advocated for AC. Tesla's work on AC power systems
included the development of the induction motor and the transformer, making it practical
to transmit electricity over long distances. This laid the foundation for the widespread
use of AC in power distribution. Thomas Edison, a proponent of direct current (DC),
engaged in a battle with Westinghouse and Tesla. Edison conducted a campaign to
discredit AC, emphasizing its alleged dangers compared to the supposedly safer DC.
The rivalry reached its peak with the "War of Currents," a series of events and
public demonstrations where both sides sought to prove the superiority of their
respective systems. Ultimately, the efficiency and practicality of AC won out. The
success of the Niagara Falls Power Project in 1895, which utilized AC power generated
by Westinghouse equipment, demonstrated the viability of long-distance transmission
of electrical power.
Prior to his involvement in the electrical industry, George Westinghouse made
significant contributions to rail transportation. He invented the air brake, a system
that allowed train operators to control the braking of all cars simultaneously.
The Westinghouse Air Brake Company, founded in 1869, became a major player in the
railroad industry.
The Westinghouse Electric Corporation was a diversified company involved in various
industries, including radar, jet engines, generators, motors, and appliances. During
World War II, Westinghouse played a crucial role in the development of radar technology.
The company was involved in both ground-based and airborne radar systems. Westinghouse
engineers contributed to the design and production of radar systems that were vital
for military operations, including aircraft detection and navigation. They were
also involved in the development of jet engines. After World War II, the company
worked on jet propulsion technology. In the 1940s and 1950s, Westinghouse developed
and produced jet engines for military aircraft. Westinghouse Electric was a major
player in the manufacturing of generators and electric motors. The company produced
a wide range of electrical equipment, including generators for power plants and
motors for industrial applications. Westinghouse was well-known for its consumer
appliances, manufacturing a variety of household products, including refrigerators,
washing machines, ovens, and more. Additionally, Westinghouse Electric Corporation
had a broad range of interests and contributions including nuclear power and the
commercialization of nuclear power plants. Westinghouse was a significant player
in the broadcasting industry, owning radio and television stations and producing
broadcasting equipment. Defense Technologies: Apart from radar and jet engines,
Westinghouse had a presence in various defense technologies, including electronic
systems and missile guidance systems.
