The Osborne Executive (1984)

The Osborne Executive is one of the earliest portable computers and the one that, due to excessive pre-release information, contributed to the demise of Osborne Computer Corporation.

It's not usual to look at a vintage computer system that defines business terminology. The Osborne Effect describes a circumstance where a company releases too much information, too soon, on a new product. This pre-release can lead to the cannibalization of current sales and put the company out of business, as happened to Osborne Computer Corporation (OCC) in 1985.
