Mother's Day, a holiday characterized by warmth and gratitude, has become a prime op‐ portunity for major brands to promote their prod‐ ucts, aiming to cultivate strong consumer loyalty on this special occasion. However, this year has seen numerous instances of ineffective promo‐ tional campaigns, with one particularly memo‐ rable case being the misstep by the laundry deter‐ gent brand Blue Moon. Their slogan, "Mum, you use it first," fea‐ tured in a poster, sparked controversy among ne‐ tizens, who interpreted it as perpetuating the ste‐ reotype of mothers being solely responsible for household chores. This incident serves as a cau‐ tionary tale for companies seeking to capitalize on holidays for promotion. Firstly, companies must acknowledge the shifting public opinion on tradition. While the in‐ tention behind the promotion was to express love and gratitude towards mothers, it failed to accurately anticipate changes in societal norms and the evolving role of women. The image de‐ picted in the poster, featuring a woman engaged in household chores, reinforced gender stereo‐ types and drew backlash from the public. Secondly, promotional efforts must align with the values and emotional needs of the target audience. Bloggers criticized JD's use of the phrase "mothers are also little girls" in a text message promoting carnations for infantilizing adult women. Companies must conduct thor‐ ough research to understand the values and cul‐ tural backgrounds of their target consumers, en‐ suring that promotional messages are respectful and well-received. Finally, companies cannot underestimate the power and speed of public opinion. In to‐ day's digital age, information spreads rapidly, and even minor incidents can escalate into fullblown controversies online. Proper management of public opinion and timely responses to crises are essential for safeguarding a company's repu‐ tation. In conclusion, the failure of Blue Moon's Mother's Day promotion offers valuable lessons for companies. In future marketing endeavors, it is crucial to anticipate and address the chal‐ lenges posed by shifting public opinion while prioritizing the values and emotional needs of the target audience.
