Film and TV writers are to stage their first strike for two decades, after last-minute talks failed. The WGA wants writers to receive a slice of the additional advertising revenue that studios make when TV shows are streamed over the Internet. It also wants an additional reward for creating bespoke digital content for the Internet or mobile devices. Another key issue is how to split DVD revenue. Consumers are expected to spend $16.4 billion (E11,3bn) on DVDs this year, according to Adams Media Research, but writers receive only about 3 cents on a typical DVD selling for $20.
