The BBC have long had a history of deciding that someone is entertaining, and then forcing them onto the viewing public until eventually the suits get the messages that the viewing public does not actually agree with them.
Their most recent example of that approach was the Mayo/Whiley abonination which took one seasoned and popular broadcasteroff the station altogether, and put the other one back where she started.
Cast your minds back to Patrick Kielty, who cropped up everywhere and anywhere, much like Mr Ranganathan is doing now - it took months of his gurning presence for the hierarchy to accept that the viewers didn't find him as irresectable as the suits clearly thought they should, and he was finally dropped.
It's what happens when you employ people who are not really qualified for what they do, give them other people's money to spend getting it wrong endlessly, and then avoid any sanctions of encouragement of any kind for them to actually do their jobs properly.
Don't worry, there will be someone else along in a minute.
