Much of the turmoil we are seeing today in the media and communications industry can be attributed to the emergence of hypercompetition, where companies that were previously partners, and for technical or other reasons isolated from each other's core business, are now crossing value chain chasms and targeting their partners' customers. Apple, a computer company, moves into online media. AT&T, a network operator, offers television. Sky, a TV company, offers broadband. For the owners of each company these initiatives create growth opportunities, but for the industry as a whole there is a cumulative disruptive effect.
My colleague, Martin Olausson, has just published a White Paper on Media Hypercompetition that discusses these issues in more depth. It's available for complimentary download
