From a purely superficial viewpoint, Batman has an overwhelming 'coolness' factor which few comic-book characters (or fictional characters in general) can rival. He's a billionaire playboy who lives in a huge Mansion. His basement is a large cave filled with fancy computers cool trophies like a giant T-Rex and Lincoln penny. He's got a cool outfit which allows him to blend into the shadows and strike like a ninja, while simultaneously allowing him to shine as a hero. He's got state-of-the-art tech, including cars, planes, boats and other assorted gadgets. He's a master of all martial arts, a skilled driver, pilot, diver, escape-artist and detective. He's also an extremely intelligent person, virtually a genius. And he spends his days patrolling an awe-inspiring gothic yet modern city filled with a seemingly endless supply of psychopaths, super-villains and other criminals for him to take down! Basically, being Batman is like being the ultimate video game character in the ultimate gameplay environment!
Then there are the deeper aspects to his character. A tragic backstory, rooted in the simplest of emotional reactions - the fear of losing loved ones and the desire for retribution, which we can all relate to on some level. Multiple personalities and an 'identity crisis' that could well be the subject of a psychology dissertation (not to mention of course the fascinating psychology of his foes). The idea of vigilantism and its role in modern society; whether it helps or hinders the justice system, are questions that frequently come up overtly or subtly in Batman works. And I'm barely scratching the surface here...
In terms of media exposure, Batman is second-to-none compared to any other comic-book hero. Leaving aside the sheer volume of material, let's consider the quality instead. The most iconic and critically acclaimed superhero animated series today is BTAS, and the most iconic and critically acclaimed superhero movie series is the Nolanverse Batman trilogy. Also, for a long time, Adam West's Batman TV show was arguably the most successful television adaptation of a superhero property, and I dare say that perception still lingers among many.
Batman has also had SO MANY more iconic and popular comic-book stories than most of his peers. Year One, The Dark Knight Returns, The Killing Joke, The Long Halloween, Dark Victory, No Man's Land, Knightfall...the list goes on. Ask the average comic-book reader to name ten most iconic Superman stories, and he won't be able to rattle of the names as quickly.
Ultimately, I think there's a strong sociological aspect to Batman's popularity as well, especially in comparison to Superman. As human beings, most of us aren't selfless beings who will devote all our abilities and resources to making the world a better place, or who feel a moral compulsion to do so. But most of us, depending on the circumstances, would love the chance to be able to set right whatever we feel has gone wrong, either in our lives, or in the world at large...out of a sense of justice or of retribution. Basically, if one is walking down a street and sees a kitten trapped in a tree, IMO, most people wouldn't seriously consider trying to get the kitten down if its too much trouble, or alternatively, wouldn't feel much guilt for not trying. But if one if walking down the street and either gets mugged, or sees someone getting mugged, many would love the chance to be able to chase down the mugger and dole out punishment. Those are the sub-conscious instincts and tendencies in us that we see exemplified in Batman, which leads us to identify with him to a larger degree than we would with Superman.
I agree there. But it really goes beyond continuity and timelines. Batman's world has a certain timeless quality to it. Broadly speaking, there are major events in the characters' lives across mediums which do signify the passage of time (Batman taking Robin on as a partner, Robin becoming Nightwing, Barbara going from Batgirl to Oracle etc.) But you can easily pick up the start of any Batman comic story, or watch any Batman movie, or an episode of any Batman cartoon, and subtle nuances of continuity aside, immerse yourself in the universe...safe in the knowledge that there is a kind of consistent history, an amorphous 'pattern' replicated across all the various incarnations of the Dark Knight.
Its the reason why DC was able to get away, initially, with the 'soft reboot' of Batman for the New 52. Because even though this was technically a new continuity, you can easily get a sense of the weight of Batman's history (both that of the character and his world) and how this universe came to be, without having to get a strict recap of the backstory in the new continuity. After a point, it doesn't really matter how exactly Batman's first encounter with the Joker went...as long as you read a Batman vs Joker story now and get a sense of the years-long eternal war between the 'unstoppable force and the immovable object' (in the Joker's own words from TDK!)
