Supposedly (since I haven't seen the print ad) CBS bought this embedded video ad in Entertainment Weekly to advertise their show "The Big Bang Theory". And interestingly enough, the ad mentioned "Physics Today".
The video, which is activated when the magazine page is opened for more than 5 seconds, opens with Jim Parsons, the actor who plays Sheldon Cooper, a theoretical physicist on the television sitcom The Big Bang Theory, welcoming readers to "the current edition of Physics Today" before finding out he has been duped into supporting a different product.
You can find the video at the link above. Still, is this a preview of what's to come with print ads?
