On a serious note, aside from these MJ-related websites and social media accounts, I haven't seen any ads or marketing for Thriller 40 recently. Meanwhile, the new Queen album re-release is already getting a bunch of publicity thanks to "Face It Alone".
Also, this is kind of off-topic, but I would argue that Queen is more popular now than when Freddie was alive. In the late 80's (especially in America) their albums didn't sell as well as their earlier material, not unlike MJ's sales in the late 90's til 2009.
As morbid as it sounds, when both Freddie and MJ died, they both became modern myths: like, it's impossible for younger people to understand how talented both men were since they can only hear stories from older generations or watch decades-old footage.
