On Saturday, May 2nd, the company released some videos filmed on April 30th for their new advert “Sing.” The vids show a gigantic karaoke party of about 13,000 people gathered in the square singing “Hey Jude” by [The Beatles](https://www.trendhunter.com/trends/candlelight) and a number of other songs that are not included in this video. Over 2,000 microphones were distributed among the crowd, while lyrics to the songs were shown on gigantic screens, just like at a real karaoke bash. The crowd seemed to be having a great time, but was suddenly stunned when an image of singer Pink was transmitted onto giant screens hanging over the square. And they were then sent into a frenzy when cameras panned around to reveal that the singer was at the event in person. “Sing” was created by super advertising agency [Saatchi & Saatchi](https://www.trendhunter.com/trends/the-honest-dad-unboxing). ## Trend Insights (Trend Hunter) - Score: 3.8/10 - Popularity: 25% | Activity: 82% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Marketing](https://www.trendhunter.com/marketing) > [Publicity Stunts](https://www.trendhunter.com/publicitystunts) ## Key Themes ### What's Driving This Trend - **Karaoke Flash Mobs:** Karaoke flash mobs are a unique form of surprise entertainment that can be used for marketing campaigns or public events. - **Crowd Participation Marketing:** Utilizing large crowds in marketing campaigns is a fresh and impactful way to increase brand awareness and engagement. - **Event Technology:** Advanced event technology, such as distributing microphones and displaying lyrics on screens, can enhance the experience for attendees. ### Who This Affects Most - **Advertising:** Surprise entertainment marketing campaigns are a disruptive innovation opportunity in the advertising industry. - **Event Planning:** Planning and executing large-scale events that incorporate unique and memorable elements such as karaoke flash mobs is a potential innovation opportunity in the event planning industry. - **Technology:** Developing and implementing advanced event technology, such as screen displays and microphone distribution systems, is a potential disruptive innovation opportunity in the technology industry. ## Related on Trend Hunter - [Karaoke Christmas Trees](https://www.trendhunter.com/trends/holiday-tree-display.md) - [Artful Illusory Ads](https://www.trendhunter.com/trends/illusion-artwork.md) - [Germ-Killing Karaoke Pop-Ups](https://www.trendhunter.com/trends/airaoke.md) - [Beer-Pouring Party Billboards](https://www.trendhunter.com/trends/jubel-billboard.md) - [AI-Powered Karaoke Apps](https://www.trendhunter.com/trends/mayk.md) - [Rage-Relieving Internet Tours](https://www.trendhunter.com/trends/rage-against-big-internet-tour.md) - [Rewritten Christmas Song Ads](https://www.trendhunter.com/trends/hijacking-christmas.md) - [Nostalgic Light Board Toys](https://www.trendhunter.com/trends/litebrite.md) - [Lyrics-Inspired OOH Campaigns](https://www.trendhunter.com/trends/lyricsinspired-ooh-campaign.md)
