Love Is... is the name of a comic strip created by New Zealand cartoonist Kim Casali (nee Grove) in the late 1960s. The strip is syndicated worldwide by Tribune Media Services. The cartoons originated from a series of love notes that Grove drew for her future husband, Roberto Casali. The strip was first published in 1970, under the pen name "Kim", and was syndicated soon after. One of her most famous drawings, "Love Is...being able to say you are sorry", published on February 9, 1972, was marketed internationally for many years in print, on cards and on souvenirs. The beginning of the strip coincided closely with the 1970 film Love Story. The film's signature line is "Love means never having to say you're sorry." At the height of their popularity in the 1970s the cartoons were earning Casali £4-5 million annually.
