(Telecompaper) The installed base of the TikTok app among Dutch young people has grown extremely fast over the past year, according to research from Telecompaper covering the second quarter. The installed base has quadrupled to 28 percent from 7 percent year-on-year among those aged 16-19 but it is probably much higher still for those younger than 16, as TikTok is particularly popular among young children. For all Dutch people (16-80 years old), the installed base jumped fivefold to 11 percent at the end of June, from 2 percent the year earlier.
