The first radio shows for children were heard only on local stations, such as Uncle Wip, which was on Philadelphia’s WIP in 1921. The best-known host of this kind of show was Uncle Don Carney, who became a radio institution with his show from New York’s WOR (a 50,000-watt station that could be heard in seven states). His ad-libbed program of conversation and nonsense songs began in 1928 and ran until 1949.

Network radio programs geared especially for young listeners began with The Adventures of Helen and Mary, which debuted over CBS in September 1929. In 1934 the series was given an overhauling and a new title, Let’s Pretend, under which it continued until 1954. A half-hour show broadcast on Saturdays, Let’s Pretend featured well-known fairy tales, dramatized by an all-juvenile cast.

Late-afternoon serial adventures for youngsters began with Little Orphan Annie, first broadcast over WGN radio in Chicago in 1930. Annie was first a comic strip, created in 1924 by Harold Gray for the Chicago Tribune, which owned WGN. The radio series graduated to NBC-Blue in April 1931. The show’s format set the standard for juvenile adventure serials, running for 15 minutes each weekday, with an open-ended story line that featured Annie vanquishing a procession of gangsters, spies, and pirates in a variety of far-flung locales. Annie’s longtime radio sponsor was Ovaltine, a malt-based milk flavouring, and the program thus inaugurated two other traditions: the long commercial and the premium that listeners could obtain by mail for a nominal fee and a remnant of the product’s packaging.

Comic strips such as Annie provided the basis for many long-running radio adventure serials. They had a preexisting base of fans, and radio show and newspaper strip helped promote each other. Dick Tracy, Superman, Terry and the Pirates, Jungle Jim, Don Winslow of the Navy, and Mandrake the Magician were among the comic characters who came to radio during the 1930s and ’40s.

Captain Midnight began in October 1939 as a regional series; it transferred to the Mutual network in September 1940 and remained on the air through December 1949. Midnight was actually Captain Red Albright, a former World War I flyer and commander of the flying Secret Squadron, who was dedicated to stopping the fiendish Ivan Shark, who wanted to take over the world. During World War II, the focus changed from rooting out Ivan Shark to defeating the Nazis and the Japanese.

One of the most popular daytime action adventure shows was Jack Armstrong, the All-American Boy, produced by the Hummerts and sponsored by Wheaties cereal. It made its debut on July 31, 1933. Jack was the star athlete and hero of Hudson High School; his adventures took him to exotic locales around the world.

A show that owed much to the juvenile serial drama format and that began as a weekday afternoon show although it soon moved to prime time, was I Love a Mystery, considered by many to be the ultimate radio action-adventure series. The brainchild of Carlton E. Morse, its heroes were Jack Packard, head of the A-1 Detective Agency, and his partners, Doc Long, a hard-fighting, hard-living Texan, and Reggie Yorke, whose seeming British reserve concealed an eagerness for a good brawl. Together they traveled the world and found blood-curdling terror, mysterious women, and hidden danger.

Sports

Sports coverage on radio began on April 11, 1921, when KDKA in Pittsburgh broadcast the first live sporting event: a boxing match described by local newspaper reporter Florent Gibson. The first live baseball game was a Pittsburgh Pirates–Philadelphia Phillies game covered by announcer Harold Arlin and broadcast by KDKA on August 5, 1921. Football and tennis had been broadcast by 1922; by the fall of that year, football was regularly scheduled on New York’s WEAF. Graham McNamee, a cub announcer, was soon called upon by WEAF to broadcast several sporting events, including championship fights and the World Series starting in 1923. McNamee became NBC’s top sports announcer, presiding over football, baseball, and boxing. He infused his sportscasts with human interest and drama and became the first important play-by-play man.

Ted Husing became CBS’s answer to McNamee. He had a beautifully smooth voice, with a tone that he had achieved in part by intentionally having his nose broken and reset. Husing’s polar opposite in vocal quality was gravel-voiced Clem McCarthy, whose main interest was horse racing. McCarthy frequently covered the Kentucky Derby, memorably calling the victories of Seabiscuit and Whirlaway. McCarthy covered boxing as well, a highlight being his passionate description of Joe Louis’s victory over Max Schmeling in 1938. Also popular was Bill Stern, who from 1937 to 1956 had a 15-minute show that offered breathless and often fabricated accounts of amazing events in the lives of sports greats; Stern tried to cover himself by noting that the stories were “some real, some hearsay.”

Throughout the years, baseball and football games began to be transmitted regularly within their local markets by sportscasters, who became the official voices of their teams. Many of them developed highly personal styles with trademark phrases, such as Mel Allen’s “How about that!” after a Yankee hit a home run. Red Barber began calling Brooklyn Dodgers games for New York’s WHN in 1939, and his folksy but literate style was a revelation. Much of Barber’s style was carried on in television well into the 21st century by his onetime broadcasting partner, Vin Scully.

News

News was certainly a part of radio’s heyday; one of the first landmark broadcasts was on November 2, 1920, when KDKA in Pittsburgh signed on—from a makeshift studio in a garage—and an announcer read the returns of the presidential race between Warren G. Harding and James M. Cox. The range of the 100-watt station was unknown at the time, and listeners to KDKA were asked to send in postcards if they were able to hear the broadcast. (A few thousand people may have tuned in.) By 1928 CBS and NBC were providing full live coverage direct from the Democratic and Republican conventions. When both networks presented live coverage of Herbert Hoover’s inauguration, they received a huge response from listeners.

Clearly, the public wanted more news on radio. Radio could broadcast news as it happened, which newspapers could not do. By the late 1920s the newspaper industry saw broadcasting as a distinct threat and imposed restrictions on radio stations that were using the same wire services that supplied the print media; stories were not to be broadcast until they had already appeared in newspapers. As a result, the national networks began building their own news-gathering services.

During the early 1930s, radio news coverage increased in quality and quantity. Key stories covered by radio included Franklin D. Roosevelt’s first inaugural speech on March 4, 1933; the kidnapping of the infant son of aviator Charles Lindbergh and the subsequent trial of Bruno Richard Hauptmann; and the crash of the Hindenburg.

As news became an integral part of each broadcast day, several commentators and newsmen became well known. H.V. Kaltenborn was one of the earliest radio commentators, making his radio series debut in 1922; he became known for his instant and lucid analyses of news events as they happened. His ability to translate several languages made him especially valuable as tensions rose in Europe in the 1930s. Lowell Thomas, a globe-trotting adventurer, brought his experience to radio in 1930 and continued delivering his daily 15-minute newscasts through May 1976. Thomas’s broadcasts were free of any personal bias; this could not be said of Walter Winchell, who breathlessly rattled off a combination of news and show-business gossip, much of it vitriolic, punctuated by the dots and dashes of a telegraph key.
