Samsung's "Galaxy Gear" watch came out last year. It's basically a cellphone you wear on your wrist. This is basically a daydream people have had since Dick Tracy's Two-Way Wrist Radio, and it's always been the stuff of Science Fiction.
Samsung knows this (Or at least their advertising firm does) and so they put together a commercial that's nothing but clips of people talking into their wrists from a dozen SF shows and movies.
Babylon 5 turns up! Twice!
Various lesser SF franchises make appearances as well...
Special thanks to "Sinclair" from http://www.b5tv.com for pointing it out to me!
