As implicações que a Internet trouxe às nossas vidas num documentário a não perder. Disponível no sítio do costume.

• Primeiro episódio: The Great Leveller (no iTunes).

  Since its birth almost twenty years ago, the World Wide Web has transformed our world : A quarter of the planet is now online and able as never before to communicate, publish, and garner information seemingly without limits. But will the Web’s empowerment of ordinary people endure? As part of the BBC’s internet season, the computer expert Doctor Aleks Krotoski starts a four part series (this week) documenting the Web’s remarkable growth and asking if the old hierarchies it challenges are managing to stage a counter revolution.

• Segundo episódio: Enemy Of The State (no iTunes).

  How has the online world impacted on global politics? Twenty years on from the invention of the World Wide Web, Dr Aleks Krotoski looks at how it is reshaping power.

• Terceiro episódio: The Cost Of Free (no iTunes).

  How commerce has colonised the web – and how web users are paying for what appear to be free sites and services in hidden ways.

• Quarto episódio: Homo Interneticus (no iTunes).

  Dr Aleks Krotoski concludes her investigation of the internet twenty years on by asking whether our brains are being rewired by the net. Are Facebook and other social media infantilising and corrupting young minds, or will they encourage a new cooperative way of thinking?
