In my R&D role I naturally fly the flag of digital over hard copy. I've passionately argued the benefits for a number of years.
But I do really like the following RS Catalogue vs Web viral marketing campaign below from RS Components.
For a company like RIBA Enterprises that does digital and hard copy RIBA Product Selector and digital and hard copy NBS it's quite relevant. It nicely shows that not all users have the same requirements.
