This week’s Digital Health Observer covers TheraBreath’s ‘P.S. Your Breath Stinks’ campaign, created by Kill Boring Dead, which lets Australians anonymously send a surprise product package to someone with bad breath and turns an awkward health taboo into shareable social content. We also look at data-stream analysis showing ad placements in roughly half of monitored ChatGPT responses in Australia, with telco, energy and travel brands among the first categories buying into the conversational AI format. Plus Meta has removed 750,000 under-16 accounts across Facebook and Instagram as Australia’s social media age ban takes effect, materially changing local audience composition, reach and targeting data.
