This coverage by Variety of the legal challenges to the Paramount-WB merger is intriguing.

Are blockbuster films a separate market? Or are they interchangeable with other forms of entertainment?

The $111 billion Paramount–Warner Bros. merger may hang on that question. On July 13, a coalition of 12 states sued to block the deal, arguing that it will lead to excessive concentration in the theatrical and basic cable markets. The strongest claim may be that the combined entity will control 30% of the market for “anticipated top-grossing films.”
