The II V I progression is used mostly in jazz music. They add a nice resolving feel to the root chord. For example instead of resolving from E7 to A7 you would now resolve to A7 by adding a II V progression which would be (B-7 E7) then finally A7 the I chord.
You could consider this type of blues progression a Jazz Blues Form. The II V chords are highlighted in blue. See the attachment below.
