Casey Kasem, who entertained radio listeners for almost four decades as the host of countdown shows such as "American Top 40" and "Casey's Top 40," died early Sunday, according to a Facebook post from his daughter Kerri Kasem.
The news was confirmed by Casey's Kasem's agent, Don Pitts.
Casey Kasem was 82 and had been hospitalized in Washington state for two weeks.
"Early this Father's Day morning, our dad Casey Kasem passed away surrounded by family and friends," Kasem's children -- Kerri, Mike and Julie -- wrote in a statement released by Kasem's representative, Danny Deraney.
"Even though we know he is in a better place and no longer suffering, we are heartbroken ... The world will miss Casey Kasem, an incredible talent and humanitarian; we will miss our Dad."
Kasem's longtime friend, Gonzalo Venecia, and his younger brother, Mouner Kasem, were also with him when he died at St. Anthony's Hospital in Gig Harbor, Washington, at 3:25 a.m. Sunday, a family member said.
Casey Kasem had been suffering from Lewy body disease, the most common type of progressive dementia after Alzheimer's.
He had recently been the subject of a bitter court battle involving three of his children by a previous marriage and his wife, Jean.
His oldest children, who challenged their stepmother for control of Kasem's medical decisions in his last months, are not fighting his wife for possession of his remains, a family member told CNN Sunday.
Daughter Julie Kasem will host a memorial celebration at her Northridge, California, home on Saturday, June 21, the family member said. No other funeral arrangements were yet known.
No autopsy is expected since Kasem died under a doctor's care in a hospital. The immediate cause of death was from sepsis caused by an ulcerated bedsore, the family member said.
In May, a California judge awarded Kerri Kasem temporary power of attorney after Jean Kasem took her husband out of a nursing home and moved him to Washington amid family feuding.
A Washington judge later allowed Kerri to visit her father in that state.
Casey Kasem was hospitalized after an argument between Jean and Kerri in which his wife threw meat at her stepdaughter.
Last week, a Los Angeles County judge gave daughter Kerri Kasem the authority to have doctors end his infusions of water, food and medicine.
Kasem was already a popular disc jockey in Los Angeles when he became the host of "American Top 40" in 1970. The syndicated show, which counted down the 40 most popular songs in the United States based on Billboard magazine's Hot 100 music chart, began on just seven radio stations but quickly became a mainstay of thousands, all around the world.
"When we first went on the air, I thought we would be around for at least 20 years. I knew the formula worked. I knew people tuned in to find out what the No. 1 record was," he told Variety in 1989.
Kasem's first No. 1, concluding the "AT40" premiere show of July 4, 1970, was Three Dog Night's "Mama Told Me (Not to Come)." His last on successor show "American Top 20," almost exactly 39 years later, was "Second Chance" by Shinedown.
But the show wasn't just about finding out who was No. 1.
Its features, included biographical details on performs, flashbacks, album cuts and Kasem's "long-distance dedication" for listeners who wrote to dedicate songs to friends and loved ones far away.
Kasem, whose baritone was always friendly and upbeat, delivered these in his most sympathetic voice, warm enough to melt butter. "Dear Casey," he began, and would read an emotional letter from a listener who wanted to connect with an old flame, express regret to a new love or send wishes to a far-flung family member.
The first one, for example, was from a male listener who wanted to dedicate Neil Diamond's "Desiree" to a sweetheart named Desiree who was moving to Germany.
The show, originally three hours, expanded to four in the late '70s.
In many ways, even as Top 40 radio moved from the AM to the FM dial and took on the name "Contemporary Hit Radio," "American Top 40" remained a throwback to the way the format was in the 1960s, with frequent number jingles ("Number 29!") and a fast-moving mix, though Kasem, in temperament, practically defined the laid-back hosts of the Me Decade. (The exception to the laid-back rule was a much-copied outtake, now readily available on the Internet, of Kasem exploding in anger over a long-distance dedication that succeeded an up-tempo record.)
The show inspired several imitators, including a television version, "America's Top 10," hosted by Kasem himself.
Kasem left "American Top 40" in 1988 over a contract dispute with ABC Radio Networks and signed with competitor Westwood One, for whom he started a show called "Casey's Top 40" in 1989. The new show used a different publication's chart, but it was the same old Casey: smooth, cheerful, full of information.
"The magic of Casey is that he is the ultimate professional in whatever he does. ... He enlightens, he explores, he suggests, he provokes and he informs," fellow DJ Gary Owens told Billboard in 1997.
Kasem acquired the name "American Top 40" and in 1998 resumed hosting the program with a new syndicator. (The ABC show, with Shadoe Stevens replacing Kasem, had been canceled in 1995.) He handed off to Ryan Seacrest in 2004, though he continued with two other shows, "American Top 20" and "American Top 10," until signing off in 2009 -- as always with his trademark line, "Keep your feet on the ground, and keep reaching for the stars."
Kemal Amin Kasem was born in Detroit in 1932. He first tried radio while in high school but found he had a talent for it while serving in Korea with the Army. He was a DJ on the Armed Forces Radio Network.
After stops in several cities, including Flint, Michigan; Buffalo, New York; and San Francisco, he joined KRLA in Los Angeles in 1963, partly in hopes of an acting career. He did earn roles in a number of low-budget movies -- the most famous of which was probably "The Incredible 2-Headed Transplant" (1971) -- but his voice was always his ticket to fame, whether appearing on a Dick Clark-produced TV show, "Shebang," or voicing the character of Shaggy on the cartoon "Scooby-Doo," which premiered in 1969. (He also was the voice of Robin on "Super Friends.")
That voice became ubiquitous. He was NBC's promotional announcer in the late '70s and early '80s, and heard on dozens of commercials.
But "American Top 40" remains his legacy.
"Kasem started the show in 1970, a curious time to start a show about Top 40 mainstream pop, because the format had just been pronounced dead and progressive album-oriented radio was on the rise," wrote Susan Orlean in a 1990 New York Times Magazine profile. "He infused the show with corny reverence for conventional American values exactly when cynicism had become the more fashionable posture."
Kasem attributed his success to that everyday voice.
"It's not a clear-toned announcer's voice," he told the Times. "It's more like the voice of the guy next door.''
Kasem is survived by his second wife, Jean, whom he married in 1985; and four children.
