To be honest, this is more of a "what took them so long" type of story than anything else. The Encyclopedia Britannica has long since been replaced by Wikipedia, which is both free and more convenient. The video that you see above hasn't been true for at lest 5 years now, maybe more.
That commercial pitched 32 volume set that now costs over $400. Anyone who could have bought it has long since gotten a computer and an internet connection, which is a far better value.
