A business group that takes public deposits to produce solar lanterns and panels is waging a legal battle against ABP Pvt. Ltd, laying claim to a Bengali-language general entertainment channel run by eastern India’s biggest news company.Kolkata-based NVD Entertainments Ltd, which is part of the NVD Solar group, approached the Calcutta high court after a deal with ABP, publisher of the Bengali-language Anandabazar Patrika and English daily The Telegraph, for the takeover of the channel turned sour.NVD had in September signed a so-called memorandum of understanding (MoU), or in-principle agreement, with ABP to buy Sananda TV, which shares the name of a women’s magazine published by the news company. The channel, launched in July 2011, was to be renamed NVD Sananda.Under the deal, NVD was allowed to use the Sananda brand for up to three years, according to people familiar with the agreement. These people, who did not want to be identified, said they were surprised by ABP’s decision to share the goodwill—an accounting term meaning the intangible value of an asset—of Sananda with a little known company.
