The production company may be directly responsible for fundraising for the production or may accomplish this through a parent company, partner, or private investor. It handles budgeting, scheduling, scripting, the supply with talent and resources, the organization of staff, the production itself, post-production, distribution, and marketing. Production companies are often either owned or under contract with a media conglomerate, film studio, entertainment company, or Motion Picture Company, who act as the production company's partner or parent company. This has become known as the "studio system". They can also be mainstream independent (see Lucasfilms) or completely independent (see Lionsgate). In the case of TV, a TV production company would serve under a television network. Production companies can work together in co-productions.
