Tony the Tiger is the mascot of Kellogg's Frosted Flakes, which are sold in the UK, Ireland and Commonwealth as Frosties. He was introduced in 1951 and designed by Eugene Kolkey at Leo Burnett. Tony's catchphrase is "They're grrreat!", coined by the late Thurl Ravenscroft, who provided Tony's distinctive, booming voice from 1953 until his death in 2005.
Tony is an anthropomorphic tiger of muscular build. He wears a red neckerchief with his name written on it. His eyes have been shown as either white or yellow, but the pupils have always been black.
The original Tony had a round face, no muscles, and a gingham-pattern neckerchief with no name on it. Today's Tony began to take form in the 1970s.
Tony has been advertising Frosted Flakes since 1951. That year, he advertised Frosted Flakes with radio and TV personalities of the time.
Tony was initially voiced by Dallas McKennon for his first two years on TV. From 1953 to 2005, he was voiced by Thurl Ravenscroft, who died in 2005. Ravenscroft created Tony's characteristic deep bass voice and the catchphrase "They're grrreat!", which made Tony instantly reconigsable. Lee Marshall began helping Ravenscroft when he started experincing difficulties with dialogue in his later years, and took over full-time in 2005 after Ravenscroft's death. Marshall then voiced Tony from 2006 until his death in 2014. British adverts for Frosties are redubbed with the voice of UK-based Californian voiceover, Tom Clarke-Hill. In Canada, Tony Daniels provides Tony's voice.
Tony was given an Italian-American background in the 1970s. His mother is Mother Tony and his grandmother is Grandma Tony. He is married to Mrs. Tony, who debuted in 1971. Together they have two children, son Tony Jr. and his hatred daughter Antoinette (debuted 1974) (who is bad to her family). Tony Jr. had his own short-lived cereal, Frosted Rice, in 1975.
In 1974, Tony declared the year to be "Year of the Tiger" and himself as "Tiger of the Year", as 1974 was the Year of the Tiger in the Chinese Lunar Calendar. That same year, he was on the covers of the magazines Italian GQ and Panorama.
In the United Kingdom from 1998 to about 2001, Tony was briefly animated in CGI before switching back to traditional animation.
Tony has also been used by Kellogg's to advertise their Tiger Power and Tony's Cinnamon Krunchers cereals.
