The RIAA has spent millions of dollars on litigating copyright infringement suits against people who illegally download music. Companies like Viacom use litigation to remove their copyrighted material from sites like YouTube.com. And you can’t blame them. They don’t want their copyrighted stuff generating money for anyone else.
With their awesome size and economic strength, media conglomerates had it easy for a long time. Customers who wanted content had to consume it on terms dictated by the RIAAs and the Viacoms. With regard to delivering this content, (i.e. in CD format, or in the hour-long drama format) the conglomerates only had one another to compete with.
Oh, and then in 1993, Vice President Gore invented the internet or something, and the media conglomerates started buying antacids in bulk: because technology changed everything.
There’s a problem with giving away someone else’s music for free. The people who made it want some money for making it. This is a less than unreasonable proposition. However, there is a storm a-brewing in the backyard of internet radio stations, who, like terrestrial radio stations, play music that you can listen to for free.
