Those who participated in Wednesday's Internet blackout, as well as the scores of petitions circulating, seem to have gotten their voices heard.

Senate and House leaders announced Friday that they have postponed a test vote on legislation aimed at countering online piracy.

Wednesday's blackout attracted Internet giants like Wikipedia, one of the web's most popular sites, while a petition drive by Google garnered more than 7 million signatures. These "recent events" Harry Reid said, led him to the decision to postpone the vote on the Protect Intellectual Property Act next Tuesday. That bill, along with the House's more widely-known Stop Online Piracy Act, both seek to prevent intellectual property theft and online counterfeiting.

The Senate bill would allow the Justice Department, and copyright holders, to seek court orders against foreign websites accused of copyright infringement. It would bar online advertising networks and payment facilitators such as credit card companies from doing business with an alleged violator. It also would forbid search engines from linking to such sites.

Opponents worry it infringes on constitutional rights and could hurt the tech industry.

Since Wednesday, several lawmakers who were previously for the legislation have now come out against it.

Reid says he hopes that the "legitimate issues raised by many" can be resolved, while still protecting those hit by piracy.
