NEW YORK — Alvin Toffler, whose million-selling “Future Shock” and other books anticipated the disruptions and transformations brought about by the rise of digital technology, has died. He was 87.

He died late Monday in his sleep at his home in the Bel Air neighborhood of Los Angeles, said Yvonne Merkel, a spokeswoman for his Reston, Virginia-based consulting firm, Toffler Associates.

Toffler is credited with defining the feeling of being overrun with data and knowledge as “information overload.”
