On what basis does channel decide favourite?

In BB 8, ok tanisha and armaan were Salmans fav due to his link with Ajay D, but in the end Gauhar won. So was it that Channel wanted her as Sallu certainly did not.

In BB11 toh blatant it was, Salman favoured Shilpa. However on what basis does channel begin favouring is it due to first week public opinion polls that whoever creates most buzz will be fav no changes or is it that Salman also has input.

And now ofc we are here they have again done the same. Is Salman following channel instructions or is it him having favs as well? I know people say Rashmi is Colors lalalala but it’s clear that on WKV shukla is being let off rather lightly.

Becoming Salman fav wont win u bb..its just coincident when salman fav won bb bec luckily his fav matched with channel's fav too in those seasons ..Gauhar winning or Prince winning r big examples that not always salman fav wins ..

Its always the channel fav who wins show ..Coming to how channel decides fav ..well it depends on lot of factors like which contestant gave max buzz & footage in the season which contributed to trps(channel gets day to day ratings plus max time spent on a show so they know whose footage draws max audience) plus which contestant has been an allrounder in the season ..Allrounder means one who fights plus one who takes stand fr his friends in house plus one who is good in tasks ..one reason why sree or bani dint win as they were quitter in tasks ...so yeah thats how channel decides their fav ..
