#3 Having something for everyone

Mature content made a strong comeback in 2019 and while it still isn't injected into every single storyline, it is a lot more prevalent than it was in recent years. Beyond that, it seems like WWE focused on several previously untouched styles of storytelling in 2019, which definitely helped make it more interesting to a wider audience.
Whether that be relationship storylines, paranormal occurrences, mature content, or even something for the kids, WWE has achieved the seemingly impossible balance of pleasing everyone at once. Of course, it doesn't work all the time and some fans might be alienated here or there, but in 2019 chances are good that there's something for you on WWE Television.
In fact, between Roman Reigns, Ricochet, and Ali all being billed as super hero type characters, The Fiend taking care of the supernatural aspect, and Rusev, Lana, and Bobby Lashley covering more mature content, WWE has everything covered. They also have juggled each of these storylines in a way that is enjoyable to watch and makes the show much easier to take in.
WWE has made many strides in 2020, but one of their most important has to be how the company started making content that everyone could enjoy. It also goes a long way in helping to market the product and bring in more fans over time, which should be fun to watch play out in 2020 and beyond.
