The thing is how hard it actually is to make it big with a 4 panels comics.
First thing you got to keep in mind, and it has been shown in this thread actually, is that this isn't an internet thing, so anybody explaining how phones are a factor, ignore them, same with internet as a reason. Peanuts got popular in 1950.
Second. Do you have any idea how many people try to make a popular comic and fail? How many find some success before dying off? How many make cents for years while keeping a day job?
Probably in the several thousands, if not tens of thousands or more. I remember authors that I hadn't seen mention by people once in decades, and those are just from the internet era and that were popular enough for me to hear of.
Getting a popular comic going is the hard part; this isn't a team with an experience editor, several people doing coloring, inking, drawing, and writing, and a whole slew of marketing tactics, It's some fucker that has an idea and tries to do something, and 99,9% of the time it fails and ends in nothing. Some of it catches some attention, and then dies. Then, and only then, from within those rises some comic that might or might not be good, but it is catchy enough people keep on reading, and fans keep multiplying. Garfield's author, for example, tried several things before making Garfield with the very objective of being popular and monetizing it. He experimented and learned from his mistakes, and for what was popular at the time, before coming up with a character and slowly perfecting it so that it could keep going pretty much on its own.
Whenever you see something that does really well and you think it shouldn't, just try to remember that if it was as easy as you imagine, everyone would do it and therefore it wouldn't make as much money. Either the original creativity of coming up with it, or the process by which it reaches its current state, is what tends to be the hard limiter.
