I don't think it'd go to that extreme. Sure, the ads would be outdated, but the brands are still there.
You're still exposed to the Apple brand, and are reminded that they've been (hypothetically) awesome since 1997 and beyond. You're still exposed to McDonald's and might head out for a Big Mac (I suspect that'll stay on forever).
Maybe Volkswagens will get better in ten year's time ;-)
The problem is that no one is going to pay for you watching their ads in 10 years.
Ads are also really crafted at society at that given time. I heard a quote from a history professor who said he could teach American history using only Coca-Cola ads.
If that's the case, that's not really a problem. You get high ad exposure at the time of each episode's release, as many people will want to keep up with the show within the first few years of its airing. You're paying for their eyes.
Anyone watching it 10 years down the line is just icing on the cake for you, but that's not what you'd pay for in such a model.
