Once production is complete, distribution takes place through various channels like YouTube, TV, and websites like iTunes. Distribution companies sign deals with record labels to sell artists' music and videos to consumers. iTunes allows users to purchase and download music, videos, and more. Artists can submit applications themselves or use aggregators who correctly format and deliver content to iTunes for a fee. Independent artists may submit themselves while signed artists have labels do it. SoundCloud lets users upload, record, and share original audio, and artists can upload up to 3 hours for free or pay a subscription for more upload time.
