TikTok advertised on Facebook. Tesla used to run billboards in LA and SF and paid influencers to shill their cars. They still market quite heavily today though not through billboards (AI Day is a marketing event.) GMails invitation system was it's marketing, back in the day when people were excited about Google products. Rolls Royce sponsors athletes, which is considered marketing. They also bring cars to auto shows and to various events targeted to the luxury crowd. Tupperware's original business model was literally 100% about marketing. Most people would call it a multi level marketing scheme today.
