Using my experience, I think comedy is still a relevant form of entertainment, you just have to find it. The internet has expanded on what comedy is and where it's located. Take for instance Inside on Netflix, it expands on comedy using the the real life problems of today. Or comedy of channels that improv on whatever they're doing, like game playthroughs, and make a living on it. It depends on what relevancy means. If by having an audience or being successful in what you do moneywise, and doing that by using comedy in your job, then yes, comedy is still relevant to this day, just in different ways.
