See quite graphically how a particular construction (not very common by the way) is gaining the ground among users. The frequency is still to low, but the important thing is the slope of the tendency since the 80s. It is interesting that both verbs (to have and to be) are considered as expressing a state in some contexts (I’m tall) and therefore they don’t accept a progressive form (the -ing participe). However, some users of English as a second language (Asian, African) tend to applied the progressive to these verbs, as a form of expressing something that refers to the very present of the speaker. This tendency could be in expansion to other English speakers, even those that have English as a first language.
