NEW DELHI : The aggressive marketing campaigns for Bollywood’s top movie titles, some of which extend over a couple of months, are expected to take a significant hit post covid as studios and producers deal with limited cash flows, slashing budgets by 20-30%.“Logically, anything that requires physical interaction or engagement will go under the axe given the reasoning against gathering of crowds and the threat to everyone’s health," said Shikha Kapur, chief operating officer, studios, Eros International Media Ltd. “This is however, an opportunity to build a robust digital ecosystem that can measure impact and value going forward, and can lead to efficiencies in planning," Kapur added.Kapur, has in the past, worked on campaigns for films.
