The Washington Post reports…

Visitors to Facebook, Google, Netflix and dozens of other websites will likely be greeted Wednesday by a special message about the future of the Internet, as part of a broad campaign by the companies to stop what they say is a threat to the Web as most consumers know it. …

It’s up to each site to decide how far to go — and virtually all of them are mum about what they intend to do — but the participating businesses are expected either to write messages to visitors, or change the look of their homepages or user interfaces, in ways that make it impossible to browse those sites without learning about the issue of net neutrality. Some may post graphics like these that seek to simulate the experience of a “slower” Internet.

I wrote about the event last month. You can learn more about the movement, who is participating and what it means.
