In recent years,which of the following has caused firms to shift from advertising to PR?

A) print ads becoming more costly than TV ads
B) inability to validate product research
C) fewer people using social media
D) TV viewers being able to skip ads

With the invention of DVR and other streaming platforms, TV viewers now have the option to skip ads, making it less effective for companies to advertise through TV ads. As a result, firms have shifted their focus towards PR to gain the attention of their target audiences through different means such as events, press releases, and media coverage.
