floor footage. Originally metavid hosted house and senate committees but they were taken down in response to legal threats by CSPAN. As of late 2007 C-SPAN has adopted a more liberal copyright policy. The Metavid archive hosts the largest free & reusable archive of house and senate legislative footage. Through a partnership with archive.org the original mpeg2s are made accessible through the metavid site. The US House launched its own video site and repository in 2010 and the Senate followed in 2011. As these content sources became available, Metavid stopped archiving these chambers due to the labor-intensive process of separating proprietary C-SPAN content from public domain floor proceedings.{{Citation needed, date=August 2017
