I think the e-book and e-magazine are the first ones that came out as a digital version of the printed reading material. That was my observation. But now there are so many digital products to speak of because most of the offline businesses are shifting to online processing like the vouchers for the tickets. We were given 2 vouchers for free entrance to Hongkong Disneyland. It was sent by e-mail. One of the hottest digital product now is the Bitcoin and other crypto currency.
