Ask HN: Have TV ads changed?

i don't know why, but recently many TV ads give me an uncanny feeling

every other ad is what i would describe as "dancing happy diverse young people in colourful clothes"

when i'm watching TV ads i feel like i'm watching a corporate-monster version TikTok

the difference is with TikTok this is the content, but with TV ads it isn't even clear what the product they are advertising

how effective is the "dancing happy teenagers in colourful clothes" strategy in TV ads? teenagers typically don't watch TV

have you noticed this with TV ads in your country?
