After fan petitions and strongly worded letters from Michael Jackson's estate, Discovery has canceled its planned special about Jackson's autopsy.

The special was to air in the United Kingdom on Jan. 13. "Given the commencement of legal proceedings beginning next week, and at the request of Michael Jackson's estate, the scheduled broadcast of the medical documentary related to Michael Jackson's official autopsy has been postponed indefinitely," Discovery Networks International said in a statement.

According to Reuters, John Branca and John McClain, co-executors of Jackson's estate, were pleased with Discovery's decision.
