Research from advertising performance platform Adalytics raises questions about YouTube's advertising on children's content and whether its practices led to tracking of children across the web, The New York Times reports. Adalytics identified ads for adult products of over 300 brands designated as "made for kids," while a New York Times analysis found some viewers were taken to brand websites that placed trackers on users' browsers. Spokesman for Google, which owns YouTube, Michael Aciman said the report is "deeply flawed and misleading."
