This is true, as the American pharmaceutical company Pfizer did sponsor the 2023 Grammys.
A representative from Pfizer noted this: "We sponsored the overall Grammy's event, not any particular performance. Beyond that, we don't comment on our efforts to raise awareness"
The general public was not seen too keen on seeing this ad by Pfizer, as it appeared immediately following the performance of "Unholy" by Kim Petras and Sam Smith; many have been calling this performance "satanic".
This is backlash regarding this sponsorship because of the way it was featured during the show, immediately following this performance.
