One of the first multimedia stars, from 1934 to 1954 Bing Crosby was very successful across record sales, radio ratings and motion picture grosses. Crosby and his musical acts influenced male singers of the era that followed him, including Perry Como, Frank Sinatra, and Dean Martin. Yank magazine recognized Crosby as the person who had done the most for American G.I. morale during World War II and, during his peak years, around 1948, polls declared him the "most admired man alive," ahead of Jackie Robinson and Pope Pius XII. Also during 1948, the Music Digest estimated that Crosby recordings filled more than half of the 80,000 weekly hours allocated to recorded radio music.

Crosby exerted an important influence on the development of the postwar recording industry. In 1947, he invested $50,000 in the Ampex company, which developed North America's first commercial reel-to-reel tape recorder, and Crosby became the first performer to pre-record his radio shows and master his commercial recordings on magnetic tape. He gave one of the first Ampex Model 200 recorders to his friend, musician Les Paul, which led directly to Paul's invention of multitrack recording. Along with Frank Sinatra, he was one of the principal backers behind the famous United Western Recorders studio complex in Los Angeles.

Through the aegis of recording, Crosby developed the techniques of constructing his broadcast radio programs with the same directorial tools and craftsmanship (editing, retaking, rehearsal, time shifting) that occurred in a theatrical motion picture production. This feat directly led the way to applying the same techniques to creating all radio broadcast programming as well as later television programming. The quality of the recorded programs gave them commercial value for re-broadcast. This led the way to the syndicated market for all short feature media such as TV series episodes.[citation needed]

In 1962, Crosby was the first person to be recognized with the Grammy Global Achievement Award. He won an Academy Award for Best Actor for his role as Father Chuck O'Malley in the 1944 motion picture Going My Way. Crosby is one of the few people to have three stars on the Hollywood Walk of Fame.

Crosby was born in Tacoma, Washington, on May 3, 1903, in a house his father built at 1112 North J Street.

He was the fourth of seven children: five boys, Larry (1895–1975), Everett (1896–1966), Ted (1900–1973), Harry 'Bing' (1903–1977), and Bob (1913–1993); and two girls, Catherine (1904–1974) and Mary Rose (1906–1990). His parents were English-American Harry Lincoln Crosby (1870–1950), a bookkeeper, and Irish-American Catherine Helen (affectionately known as Kate) Harrigan (1873–1964). Kate was the daughter of Canadian-born parents who had emigrated to Stillwater, Minnesota, from Miramichi, New Brunswick. Kate's grandfather and grandmother, Dennis and Catherine Harrigan, had in turn moved to Canada in 1831 from Schull, County Cork, Ireland. Bing's paternal ancestors include Governor Thomas Prence and Patience Brewster, who were both born in England and who emigrated to what would become the U.S. in the 17th century. Patience was a daughter of Elder William Brewster (pilgrim), (c. 1567 – April 10, 1644), the Pilgrim leader and spiritual elder of the Plymouth Colony and a passenger on the Mayflower.

In 1910, Crosby was forever renamed. Six-year-old Harry discovered a full-page feature in the Sunday edition of the Spokesman-Review, "The Bingville Bugle." The "Bugle," written by humorist Newton Newkirk, was a parody of a hillbilly newsletter complete with gossipy tidbits, minstrel quips, creative spelling, and mock ads. A neighbor, 15-year-old Valentine Hobart, shared Crosby's enthusiasm for "The Bugle," and noting Crosby's laugh, took a liking to him and called him "Bingo from Bingville." The last vowel was dropped and the name shortened to "Bing," which stuck.

In 1917, Crosby took a summer job as property boy at Spokane's "Auditorium," where he witnessed some of the finest acts of the day, including Al Jolson, who held Crosby spellbound with his ad-libbing and spoofs of Hawaiian songs. Crosby later described Jolson's delivery as "electric."

In 1926, while singing at Los Angeles Metropolitan Theater, Crosby and his vocal duo partner Al Rinker caught the eye of Paul Whiteman, arguably the most famous bandleader at the time. Hired for $150 a week, they made their debut on December 6, 1926 at the Tivoli Theatre (Chicago). Their first recording, "I've Got The Girl," with Don Clark's Orchestra, was issued by Columbia and did them no vocal favors as it sounded as if they were singing in a key much too high for them. It was later revealed that the 78 rpm was recorded at a speed slower than it should have been, which increased the pitch when played at 78 rpm.

As popular as the Crosby and Rinker duo was, Whiteman added another member to the group, pianist and aspiring songwriter Harry Barris. Whiteman dubbed them The Rhythm Boys, and they joined the Whiteman vocal team, working and recording with musicians Bix Beiderbecke, Jack Teagarden, Tommy Dorsey, Jimmy Dorsey, and Eddie Lang and Hoagy Carmichael.
