India's JioStar, the TV and online entertainment venture of Reliance and Walt Disney, has initiated legal measures against rival Zee Entertainment for alleged unauthorised broadcast of Bollywood films it has the rights to, documents show.

Billionaire Mukesh Ambani's JioStar is the No. 1 player in India's vibrant $30 billion media and entertainment industry, while Zee, one of India's oldest media groups, is a smaller rival.

They are already locked in a $1 billion arbitration in London over a collapsed cricket licensing deal in 2024.

In April, Zee sued JioStar in a Delhi court for unauthorised use of its copyrighted ‌music. In an apparent tit-for-tat move, JioStar filed a case on May 4 with a legal mediation committee challenging Zee's broadcast of some Bollywood movies last year even though their rights at the time vested with the Reliance-led entity, according to legal documents reviewed by Reuters.
