Jammy and all,
Here are the pieces of information regarding this. If you want more I have posted it in the other jassi forum and the link is below.
Indian Idol is reaping benefits for Sony, but not everyone is pleased.While on one hand, Thursday means an increase in the channel's overall performance, it also means a drop for 'Jassi…' and 'Ye Meri…' on that specific day.
Indian Idol is the channel's biggest bet currently and Sony has
ensured that it is giving the show its best push. Consequently, this meant placing Idol in the Thursday 9.30 pm slot, which pushed 'Jassi…'
on the 10.30 pm band and 'Ye Meri…' on 11.00 pm. In effect, this means
that on Thursdays, original programming extends to 11.30 pm, as
against the usual 10.30 pm.
"It is just getting too late for 'Ye Meri' and hence
it makes sense to take 'Jassi…' off on Thursday and keep 'Ye Meri' on
the 10.30 pm slot."
With this, evidently Jassi becomes a thrice a week deal and 'Ye Meri'
has to continue with its Thursday battle. However, this has been a
course taken to keep the viewers as well as the advertisers happy.
