Quality marketing is fun to watch.
Hence the people (including myself) who only watch the ads. It's hardly isolated to the Superbowl—look at the millions of views which some better ads get on YouTube.
Likewise, I definitely think for many people advertising is part of the magazine experience. I certainly don't mind some of the nicer ads in The New Yorker.
Most of these "quality" commercials could swap out products and the exposure would be the same. People don't want to be sold something, they just want to absorb interesting content. That's what modern advertisement gets wrong.
I think the Get a Mac campaign, for example, is both lots of fun and directly connected to the product being sold.
Now with the internet I do not even read magazines anymore...
Online ads I block. The ads in the magazine can't spy on me or serve me malware.
