[HIGHLIGHTS] The new Max platform, a merger of HBO Max and Discovery+, promises a "Harry Potter" series

HBO Max and Discovery + will launch May 23 in the U.S. The new platform will be available at three rates, from $9.99 to $19.99 per month.

The service will also have access to content from HGTV, Food Network, or Discovey Channel. It wants to compete with the giants Netflix and Disney+, two years after the announced merger between WarnerMedia and Discovery to form a new media giant. The first series will be based on J.K. Rowling's "Harry Potter" books.
