getting forecasted on, like a domino effect, and all of that bad credit was sort of filtered throughout the financial system. >> bear sterns is rescued from impending bankruptcy by jpmorgan chase. six months later, the top mortgage giants, fannie mae, and freddie mark. leman brothers collapses without warning, and aig is seized by the fed, signaling the entire u.s. financial system is on the brink of failure. >> the government's response to the crisis was parpathetic. problems rolled in and they dealt with them on a case-by-case basis. they were just trying to stop the economy from going into a depression. >> in an effort to stabilize the economy, congress approves a controversial $700 billion bail out. >> this is truly a monumental moment in american history. >> their view was you can't just let it all go down, because if the banks go down, then the economy is in chaos. >> a lot of people lost their

homes and a lot of people lost their jobs and eventually you saw people down size and it shook out to where it ought have been from the start. >> the bailout under the bush administration is perceived by many conservatives is government overstepping its bounds and protesters launch a new movement with an old history. >> we're thinking of having a chicago tea party in july. >> that's where the tea-party movent was born. nobody found them a new job, nobody made sure their employer was solvent, so that really got people upset. >> the tea party quickly takes off, and in 2010, it helps the gop capture the house. >> the tea party morphed into something entirely different, sort of this free-floating vessel that collects anger and anxiety wherever it goes and runs on that as fuel, but the beginning is the financial crisis. coming up. >> instead of trading cassettes,

sophisti sophisticated and how they'll fight that. the huge battle against the internet site known as napster. >> the file sharing service napster was launched in 1999. >> the goal was to make music available to everyone. >> the site blind sides the record industry and permanently transforms the way music is distributed and sold. >> instead of trading cassettes, which we had been doing, songs are flying around for free like crazy. >> add its peak, 70 million users are swapping songs on napster, costing the record industry hundreds of millions of dollars in lost revenue before the service is forced to shut down in 2001. >> we started a kind of cultural revolution but didn't succeed as a business. >> nearly two years after its demise, apple launches the itunes music store, that redefines the single. >> i can't remember the last time i bought an entire album.
