Modern graphene work looks to have started in 2004, so it hasn't really been all that long considering that it takes time to work out how to produce it, how to actually make use of it, how to manufacture the things that make use of it, life span in applications, toxicity, etc. Also, any initial patents wouldn't have run out yet, which could prohibit bringing it to market. I wouldn't be surprised if it takes another 20 years to take off in actual products.
