How I Met Your Mother Is Currently Up To Season 6 :)
Season 6 is out on DVD October 3rd 2010
The sixth season will begin airing on September 20, 2010.
Season 6 will be released on DVD on Sept 27th, 2011.
Season 6 premiered on Sept 20, 2010 and concluded on May 16th, 2011.
It first aired on Jan 3rd, 2011.
No one quite knows when the show will finish, only the producers. As long as the show keeps its success, it will keep running. For example, if they decided to end it in season 1, they would make Victoria the mother. But they have decided to make a season 6, but no one knows exactly when it will end.
So far there are 18 episodes. the 21st of march is the next one
The sixth season was quite interesting and I have some of my favorite episodes from this season like last words. Quite emotional and close to real life situations. It was aired from September 2010 to May 2011 and introduced a few new characters like Zoey.
there was an advert on E4 for it today, I'm pretty sure its December 23rd :D
it has begun but stopped half way through i dont know when it will restart but if your in america its still going on
