Driving forces
Network effects
More users of a service → more attractive the service ("positive externalities")
Examples:•Telephone•Sms•Skype•Facebook•WhatsApp•….

Positive externalities: consequences
The number of subscribers of services based on networks can grow extremely fast
When there are many subscribers, they may accept to pay an higher price for the service
Typical example: a service is initially free to grow the user base, then paid
R.Polillo - March 2015
Positive feedback
If a product / service with positive externalities gains a larger market share with respect to its competitor, it will obtain larger and larger market shares, toward the 100% market share
W.Brian Arthur, “Increasing Returns and Path Dependence in the Economy”, 1994
« For whoever has will be given more, and they will have an abundance. Whoever does not have, even what they have will be taken from them. »
Matthew, 25-29
Positive feedback,"Law of increasing
returns","Winner takes all"

Product with positive externalities
Product without externalities
R.Polillo - March 2015
Consequences
First mover advantage: he who gains market shares before his competitor has a very large competitive advantage
Butterfly effect: the success of a technology may depend on fortuitous facts which afford small advantages at the beginning, which start an "avalanche effect" which may have nothing to do with its technical qualities
Standard de facto: computer industry is dominated by de-facto standards dictated by first movers (de-iure standards aften fail)

The myth of free services
The prevalence of business models in which it is not evident who pays for what

The question is how you are paying it
and if you are willing to do it"

The “filter bubble””
The variety of information is reduced by filtering algorithms, which filter away what we and our social network do not "like”“Imagine a world where you never discover new ideas” (E.Parisier)
