Content creator and actor Bhuvan Bam has trademarked 'Titu Mama', the popular character he plays in his 'BB Ki Vines' series. "There is a lot of chance for plagiarism with such characters," said Bam on the reason behind trademarking. "I...received calls saying people loved Titu Mama's performance in Bhopal whereas I have never performed in Bhopal," he added.
