Philco Corporation logo - RF CafePhilco 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) - RF CafeRadio 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.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
