1930s The Aero bar was advertised in the late 1930s with the slogan, "You get a lift".
1950s Production ceased during wartime, and the bars were relaunched in the 1950s. The relaunch campaign had commissioned oil paintings of 40 "ordinary" women, to highlight that the chocolate bars were an accessible treat for all. The slogan used was 'Different... For her, Aero - the milk chocolate that's different!". After advertising Aero from 1951 to 1957, some of the portraits decorated the York factory for decades. In 2013, Nestlé attempted to identify the models, known as "Aero girls", to better track their company history. The portraits were exhibited as "Who Were the Aero Girls? Discovering Hidden Art in the Archives", at York's Mansion House, and the project website. Some of the models were later identified as Barbara Pitt,
Janey Ironside,
Rose Wylie, Myrtle Crawford (later, Lady Acland) and Pamela Synge.
1970s In the 1970s, Rowntree's aired an advertisement in which children flew an Aero bar as if it were a kite.
1980s In 1980,
Nigel Havers featured in a train-themed Aero advertisement, which was included in the Animated Britain online project. In the late 1980s, the slogan "Each Aero Chocolate Bar Has The Nourishment Of Almost Three Ounces Of Milk" was created by Toronto advertiser John Straiton. In 1987, the advertisement won the Rotten Apple Award from the Quebec Corporation of Professional Dietitians, as the comparison between the nutritional benefit of confectionery and dairy was considered misleading. Rowntree had previously received the same Rotten Apple Award in 1984 for a similar comparison between the bar with milk in a previous advertisement. The slogan for Aero in Australia during the 1980s was ''"It's the bubbles of nothing that make it really something."'' From the 1999 redesign and "singers" advertising campaign Aero's tagline was
"Have you felt the bubbles melt?" This slogan was invented by Nick Welch, an advertiser and the father of
Florence Welch of the indie band
Florence and the Machine. In circa 1989-1993, a young couple playing chess advertisement was popular in Ireland on television.
1990s The Aero packaging in 1993 in America had the slogan, "Melt into the moment.", supported by television advertising showing a woman taking a bath in liquid chocolate. In 1996, Nestlé repackaged the Aero bar and relaunched it with television advertising that used voice-over by
Dani Behr, and the phrase "Great chocolate taste." They changed the structure of the blocks to make it easier to break into sections. The advertisement showed a woman's day dreams while floating away during eating an Aero.
2000s In 2000, Nestlé apologised and withdrew milk and white chocolate cranberry-flavoured Aero bars from the market. The accompanying slogan "Stuff Xmas! Treat yourself!", was considered potentially offensive by the
Church of England and led to the suspension of distribution. In January 2001, the packaging was described as featuring a cartoon turkey with the words; "Delicious Aero chocolate with a touch of sauciness - What could be more uplifting than bubbles that melt into delicious Nestlé chocolate?". In 2001, The Aero White was relaunched as a permanent offering with a campaign theme, "Here to Stay". In May that year, Nestlé UK's "All Bubble. No Squeak." campaign was previewed online prior to television, an unusual step at the time. It was previewed on the internet first, as the mouse character, Aeron, was computer-generated and this was considered a good strategy. The advertisement slogan, "All bubble. No squeak.", and the clip showed a man buying an Aero bar, which included a free hula-hooping mouse. He declined the mouse as the chocolate bar was considered good enough as to not require gimmickry. The animated mouse later won Best Animated Animal at the 2002 All Star Animal Awards. The promotional campaign included people in mouse costumes in Manchester providing passers-by with a hula-hoop challenge in exchange for a free Aero bar. In July 2001, presenter
Davina McCall accidentally promoted Aero during a live eviction episode of Big Brother UK. She highlighted crowd banners that stated, "Hats Off To The Bubble," mistakenly thinking that they were about evictee
Paul "Bubble" Ferguson. It turned out that they were advertisements for the chocolate bar. In 2002, Nestlé Canada's research showed that consumers would often break the Aero bar into pieces and then let it melt in the mouth to prolong the experience. Their subsequent advertising showed two women, the first biting into the bar, the other responding, "What are you doing? That's not right.". In 2007, Aero Hot Chocolate was promoted as an ideal Winter drink, with an animated bubble "Lovely Bubbly" television campaign. In 2009, skateboarder
Bob Burnquist featured in a UK ad called "feel the bubbles", filmed skating through chocolate coloured balloons, with
the Jackson 5's song
ABC playing in the background.
2010s & 2020s The slogan in 2011 was "Irresistabubble"—a revival of a 1980s campaign that also featured the same word, and was created by
Salman Rushdie, during his time as an advertising copywriter. Rushdie has said that he invented a whole series of bubble words for the campaign, including
Delectabubble. In 2012, agency Skive created the 'AeroMail' social media campaign in which consumers could "spread the bubbliness" of Aero with a digital balloon on Facebook. In 2018, The Interflex Group won the "Best use of process colours only" in the FlexoTech Awards for their work on the Nestlé Aero Chocolate Bubbles print design. The judging panel highlighted the use of
CMYK with metallic effects by lamination, achieving a 'copper' look. In 2025, Aero released a new flavour, coconut, alongside a campaign where 10 bars (not necessarily all coconut flavour) without any bubbles at all could be found on store shelves to win £10,000. ==Varieties and flavours==
