In the latest online copyright brouhaha, the British tech-news website The Inquirer reported Tuesday that YouTube has sent a letter to a woman who posted a 29-second video of her baby in which the child bopped to the music of Prince's "Let's Go Crazy." The woman, Stephanie Lenz, said that she was told that Universal Music Publishing Group had demanded the video be removed. "It was Universal Music Publishing group, and I was afraid that they might come after me," she told the Inquirer. She eventually hired an attorney who was able to persuade YouTube to restore the video. But Universal has fired back with legal action of its own.
