Pointless presenter Alexander Armstrong would be "deeply upset" if the popular programme changed in any way or switched channels, he said.
The TV host, who has fronted BBC1´s daytime quiz show since it began in 2009 alongside Richard Osman, made the comments following The Great British Bake Off's move from BBC after its production company Love Productions sold the rights to Channel 4.
Alexander, 46, told the Press Association he is sure Pointless will stay with the BBC, due to the channel's "very strong bond" with the quiz show's producer Endemol UK.
He said: "We are already talking about two more years (of making the show) at least, and we won't be moving to Channel 4. We won't be doing any of that.
"I don't think it ever would (move). There's something very nice with the nature of Endemol's relationship with its broadcasters. I think it would be exceedingly unlikely.
"There's a very strong bond between our production company and the various broadcasters it works for."
He added he would be "very, very surprised" if the programme moved and he "could not be happier" to have Pointless on BBC1, where it now belongs after switching from BBC2 in 2011.
Aside from Pointless - which has seen Alexander and Richard film more than 200 more episodes over the past eight months - the TV star and comedian is preparing for the release of his second album.
After his successful 2015 debut record A Year Of Songs, Alexander will release his follow-up effort, Upon A Different Shore.
He described the album as "really bonkers" due to its genre-crossing range of songs.
He said: "If you look at the track-listing, you might just think we've lost our minds. It is incredibly eclectic, but it makes sense."
The track-list includes versions of tracks including Pink Floyd's High Hopes, Fields Of Gold by Sting and a piece by singer-songwriter Peter Skellern called Hymn Song.
He explained that he wanted to take the listener on a journey, and that he was keen this record should not play like a greatest hits collection.
Alexander said: "I love those albums that take you on a really big journey, where one song bleeds into the next and there is a thematic, narrative journey you go on."
His broad taste in music is something he wanted to be prominent on the album, on which he also makes his debut as an oboist.
He said: "Music has been - even more than comedy - it is everything to me. From the age of seven I've been a singer, and I was semi-professional in my early 20s."
He added that the album is "the perfect contemplation" for life and that the unlikely marriage of songs has an "enormous relevance to the passing of someone".
Alexander Armstrong's Upon A Different Shore will be released on October 28.
