Public television writers repped by the Writers Guild of America have unanimously ratified a new four-year pact.

The WGA said the deal, announced Wednesday, covers made-for-Internet programming for the first time and preserves payments for digital reuse. WGA employees at the stations will receive rate increases of 2% in the second year and 2.75% in the third and fourth years.

It takes effect immediately and covers about 300 members who write content for the three major producers of public television programming — WGBH, WNET and KCET — as well as other production companies that produce content for PBS.

“Public television and its continuing innovations in digital media continue to make it one of the most important and trusted sources in America and around the world for independent journalism and documentary production, as well as superior programming in the arts, history and science,” said Michael Winship, president of the Writers Guild of America East.
