Sony and Zee disagreed over more than 20 compliance issues, including the Indian firm's failure to dispose of some Russian assets and its $1.4 billion Disney cricket rights deal, before their India merger was scrapped, according to internal emails reviewed by Reuters. The collapse of the deal is a bigger setback for Zee, one of India's best known TV networks that started in 1992 but has seen its business struggle over the years. Emails show there was a face-off between Sony and Zee about four Russian subsidiaries that dealt in content creation and distribution, as the merger agreement had stipulated no dealings with entities based in countries under U.S. sanctions.
