1. IDEA 1 OF 8

   Information industries follow a cycle

   Wu argues that information technologies follow a pattern he calls the Cycle.

   Each begins as an open, chaotic field of inventors, then gets taken over by a powerful monopoly or cartel.

2. IDEA 2 OF 8

   Telephones became a monopoly

   Wu describes how the telephone began with many competitors but became controlled by AT&T.

   The company dominated American communication for decades. Early rivals were bought or squeezed out, which left one firm in charge of the network.

3. IDEA 3 OF 8

   Films fell under studio control

   Wu describes how early independent filmmakers were overtaken by Hollywood studios.

   The studios controlled production and cinemas. Owning the makers, the distributors and the theatres gave a few firms power over what audiences could see.

4. IDEA 4 OF 8

   Radio was consolidated

   Wu describes how radio began with amateurs but was taken over by big networks such as NBC.

   Once the money and the licences were in the hands of a few large firms, the early freedom faded.

5. IDEA 5 OF 8

   Television was controlled

   Wu describes how television was shaped by a few networks and government decisions.

   Innovation was often slowed. When a few firms control what reaches viewers, new ideas can find it hard to get in.

6. IDEA 6 OF 8

   Cable challenged the old order

   Wu describes how cable television broke the networks' hold but created new giants.

   Cable offered viewers more choice, yet over time it too became dominated by a small number of large firms. The pattern repeated.

7. IDEA 7 OF 8

   Control holds a master switch

   Wu argues that whoever controls the key infrastructure holds a master switch over information.

   This gives great power. A single company that owns the channel can decide which voices are heard and which are shut out.

8. IDEA 8 OF 8

   The internet could close

   Wu warns that the open internet could follow the same pattern.

   He calls for protecting openness. Today's open platforms could be tightened by a few powerful firms, as earlier media were. Wu argues that keeping it open needs active care.
