Sensor Tower data shows that Pfizer has leaned heavily into video advertising to reach consumers with YouTube, Desktop Video and OTT platforms representing more than half (53%) of US ad spend for the company in 3Q24, up from ~30% in the prior year, perhaps driven by the broader types of audiences and age demographics using these platforms. Additionally, both Pfizer and Eli Lilly's DTC telehealth platforms have exhibited significant growth in mobile web and desktop traffic since launch.
