What impact has social media, especially Facebook, had on the entertainment business?

[Pequeño Jimmy]

and what impact will it leave in the future? positive or negative?

Yes, social media provides new marketing methods and all, but then again, most of the entertainment business' revenue comes from advertisers. so, social media might be an ally and an enemy at the same time.

and i dont believe selling DVD's or songs help, as final customers tend to find ways of getting them for free. and making laws and regulations against it will hurt the relationship between the suppliers and these final customers.

Social Media sites such as youtube may have a downside on entertainment business specially movie makers. There are a lot of locally and internationally produced movies are being recorded and uploaded in youtube thus instead of watching movies in theaters/cinemas, movie goers are now resorting to these video sites to watch it for free.
