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, who added that a memorial service will be held Friday.
      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.
    
  
    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.
    
  
    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.")
