Children will be taught internet safety in schools with the launch of a new "green cross code" for the web.
As part of the new internet safety strategy, internet service providers will be independently reviewed to make sure they are doing enough to keep children safe.
The strategy will also require social networking sites, retailers, schools and charities to adhere to a "digital code" and by 2011 primary school children will be taught internet safety from the age of five.
The strategy, called Click Clever Click Safe, was produced by the UK Council for Child Internet Safety. The council was set up after Tanya Byron's review of inappropriate material on the web.
Children's secretary Ed Balls said, "New standards on internet safety mark a watershed in government and industry cooperation. I am pleased some of the biggest names in the industry, including Microsoft, Google, and Bebo are giving it their backing. In addition, our new digital code will provide a handy tool for children and parents to give them the confidence to know how to protect themselves online."
