Nielsen data also showed that about 88 percent of gambling advertisements appear on websites, including social media platforms, which are not as well-regulated as television adverts. That on its own eclipsed the 170,000 adverts for offline gambling during the same two-month period last year. Roughly 273,000 of them were for online gambling. The money allowed for a total of about 370,000 gambling advertisements during the two-month period, according to Nielsen. FairPla圜asino has spent 3.3 million euros, followed by BataviaCasino, which paid 3.2 million euros for advertising, and the 2.6 million euros spent by Tombola, the newspaper reported. The two firms are owned by the Dutch state. Of the eleven, Holland Casino spent the most money on advertising during October and November, dropping 6.4 million euros on commercials for its online offering. Eleven casinos in the Netherlands have a license for online gambling. The rise in gambling ads is mainly due to the legalization of online gambling in October. This year there were 366,631 in that same period. In October and November 2020, there were 170,066 gambling commercials in the Netherlands. The number of gambling advertisements has doubled since last year, the Volkskrant reported based on research by Nielsen.
