The 170 organisations involved - including
Amazon, Reddit and
Netflix - are preparing to alter how their services are displayed on Wednesday 12 July as a warning against FCC proposals for deregulating how internet service providers (ISPs) treat customers.
While it isn't clear exactly what measures the internet companies will use to protest, it could mean, for example, slower loading times for users, as well as altering the appearance of their sites.
The websites for Amazon and Netflix will display a message explaining that their sites could be slower because of the deregulation - but there is no plan to throttle the sites, as others may do.
