The Internet entitlement mentality

January 19, 2010 4:24 am | by Jason Lomberg, Technical Editor | Comments

The Internet has connected the world as never before. But it’s also given rise to a pernicious entitlement mentality. A whole generation has been conditioned to expect everything for free (and quickly). Coupled with the practice of file-sharing, this entitlement mentality is destroying two industries—print media and the recording industry.
