[Futurama]Why does everyone in the year 3000 have such an incredible knowledge of the 20th century

I understand why they might know about the major events (some presidents, wars) but how do they know about all the pop culture that they reference?

The second coming of Jesus destroyed all video tapes on earth, all that was left was print media. 

The longest lasting print media was glossy magazines since newspapers and books generally disintegrated or rotted. This resulted in the only "history" available being tabloids and propaganda material. 

People read this and this alone, resulting in a period of sixty or so years being the only history known in the future.
