First, sell the broadcasting rights. A good TV series can't worry about making money. On the contrary, once the TV series is produced, major TV stations and online platforms will compete to buy the right to broadcast TV series, especially the right to premiere it.
Second, sponsorship fee
Many TV dramas will look for investors before shooting. Some of these investors may be for copyright income, while others are purely for advertising sponsorship.
Third, the premium income At present, many TV dramas that actors participate in are basically invested by the companies they signed. Once the TV series they participate in is on fire and their popularity is improved, in addition to the income of TV itself, their own worth will also rise.
Fourth, copyright income.
If a TV series is very popular, then its commercial value is high. At that time, many people will naturally want to rub the popularity of this TV series. For example, some clothing brands may use some characters, some toy companies may design cartoon characters of the protagonists in TV dramas, and some game companies may directly adapt them into games.
