Amazon and TikTok’s Cannes debut—a complete guide to tech on the Croisette

A new crew of internet advertising darlings is trying to park their yachts and lay down their beach blankets along the Cannes coast at this year’s advertising festival. Amazon, TikTok, and Roku are all trying to make their marks with their first official appearances at the yearly marketing confab in the South of France, which runs from June 20 to 24. Netflix and Apple are also sending people to the event, only with a less obvious footprint, according to people familiar with their plans.
