Switching Costs & Microsoft
“It is this switching cost that has given our customers the patience to stick with Windows through all our mistakes, our buggy drivers, our high TCO [total cost of ownership], our lack of a sexy vision at times, and many other difficulties […] Customers constantly evaluate other desktop platforms, [but] it would be so much work to move over that they hope we just improve Windows rather than force them to move. […] In short, without this exclusive franchise [meaning Windows] we would have been dead a long time ago.”

One-sided markets
- Networks that drive most of their value from a single class of users
- Same-side exchange benefits (benefits derived by interaction among members of a single class of participant)
Two-sided markets
- Networks markets comprised of two distinct categories of participant, both of which are needed to deliver value for the network to work.
- Cross-side exchange benefits (When an increase in the number of users on one side of the market creates a rise in the other side)
buyers
sellers
Users (Windows, PS2)
Developers
(programs, game titles)
How are these markets different?

Strategies for Competing in Network Markets
- Move early
