Why does Hollywood keep churning out remakes? Some ideas

"Ghostbusters"! "Jurassic World"! "Point Break," even. We live in the remake era. Are audiences getting exhausted, or were their generations raised to love the reboot?

Another "Fantastic Four" movie? How many "Spider-Man" and "Godzilla" reboots do we really need? And yet movies, TV shows, cartoons, comics, and video games are all subject to reboots and remakes whether we want them or not.

PBS Idea Channel takes a look at why there are so many Hollywood remakes of movies from our childhood, or in some cases, from just a few years ago.

Remakes are nothing new. "Robin Hood," for instance, has been remade 11 times since its 1912 debut. Using Wikipedia's List of Remakes as a guide, PBS Idea Channel reminds us that not only are remakes more common than you think, but more of them came in the years between 2002 and 2011 than in any other 10-year period.

Just a few of the very latest remakes in the works range from "Ghostbusters" to "Point Break" to, some have said, "Big Trouble in Little China."

So why does Hollywood keep churning them out? Aside from earning a healthy profit for movie companies hoping to cash in on an already faithful fanbase, there's also a chance of making a successful movie or TV franchise based on an original that tanked at the box office -- think "Ocean's Eleven" or "Buffy the Vampire Slayer."

PBS Idea Channel also points to actor Simon Pegg, who recently said in his blog, "The children of the '70s and '80s were the first generation for whom it wasn't imperative to 'grow up' immediately after leaving school."

And guess who is cashing in on this generation of adults who still love the superheroes and characters of their childhood?

"This extended adolescence has been cannily co-opted by market forces," PBS Idea Channel host Mike Rugnetta says in the video. "Suddenly, here was an entire generation crying out for an evolved version of the things they consumed as children. This demographic is now and truly serviced in all facets of entertainment, and the first and second childhoods have merged into a mainstream phenomenon."

Or does this need to consume remade media stem back from our earlier endeavors into retail reproduction, the Industrial Revolution and capitalism?

Don't worry, PBS Idea Channel is already on the case so you don't have read scholarly essays from French sociologist Jean Baudrillard to figure out why we loved the latest "Jurassic World" movie so much.
