Mad Men is more about an idealized, distant and long forgotten world, than it is about advertising or ad agencies, or an accurate historic record. The details might be accurate, but the choice of this particular story-line, at this order, with these particular characters, is more a reflection about the mind of the show author(s) more than anything.

It's what all the authors of the series long for; a place where men looked good, got paid to do "creative" work, and had 99 "girl" problems. It's more about Today than yesteryear; the slightly more refined tastes of Porky's generation.

In the future, your series of choice might be about a gang of environmental activists who are members of an ad-busting and "culture jamming" crew, with connections to the Cribs gang, the break-dance scene, and who just happen to be mad demo coders and phreakers. In other words, the popular art depicting today's world will be a caricature reflection of whatever surviving lore, confirmed by exhaustive records, since all of those things exist today, or existed until recently. Everyone born after 1980 might as well be referred to as "cyber-punk".

It'd have been as little used as this will eventually be with no significant effect to the advertising industry.

(I mean this in a non-derogatory sense. It might eventually be used on even a lot of TV programmes, but in the grand scheme of things, we're not going to be wiping the record of advertising from the face of the earth forthwith with this.)

The above is also why I can't stand how many blogs these days don't put a publish date anywhere, for the sake of minimalism.

I think the real, unwritten reason they're doing this is to serve as an adblock for video content you 'consume' - that is, television shows and movies.

Of course, I will too, but I also want the option of viewing things through different filters. The original will exist, as will copies and variations.
