The Seven Digital Disruptions
OM Malik has a great post up, with the help of Bob Baily, CEO of PMC Sierra.
He lists Bob's five digital disruptions and adds two more.
Here they are:
MPEG/MP3 - Disrupts the music and movie business
PVRs - Disrupts the TV ad business
Broadband Entertainment - Disrupts the TV business
Digital Cameras and JPEGS - Disrupts the film business
Linux - Disrupts the operating system business
Network Computers - disrupts the PC hardware/software business
Wireless Networks - disrupts the wire line phone business
VOIP - disrupts the entire phone business
The truth is there are probably many more examples of this stuff. It's the defining characteristic of the economy in the first decade of the new millenium.
