Well Jolly bhai i will be really sad if BBC Earth is discontinued but afraid signals r not giving good feel. I agree social media accounts being inactive is not always sign of channels being pulled off but this depends on case to case basis. I can elaborate but refrain right now bcoz of paucity of time. All i can say is this is an extremely worrying sign for Sony BBC Earth.
I would ideally not want Discovery to get BBC content, purely bcoz of the fact that they cannot match packaging / presentation / content curation/scheduling which BBC can while running own channels.
Rolling over to Sony adding a new hindi movie or music channel in its portfolio. Well bhai, yes few months back i shared same opinion as urs specially after they suffered setbacks right at start of year. Expansion that too in our favorite genres was far off dream but hey hey... This has great chsnce of happening now and i will explain why. As u know Sony has lost out on YRF and 2 Filmkraft movies recently, there is possibility of other producers or bollywood houses changing to other side bcoz they realise Sony is not giving proper air time to their movies. Remember just getting money from selling rights is not enough, bollywood people want visibility for its films which helps create buzz among people thus not leaving things to fade off. Sony will surely be under pressure to launch bollywood channel to convince the concerned people.
Now coming to hindi music channel going on air... This coming to reality is again not a stretch of imagination. Just few weeks back Sony Mix got a facelift, they have made it more urban or youth centric thereby also increasing time reserved for new songs. There can be plans to start a channel for primarily catering to 80's, 90's, 2000's music which gets huge viewership and it will compete with mastiii, 9x jalwa and b4u music. Having dedicated channels for new and older music will help expand viewer base and break the overlapping which can inturn bring in more advertisers on board too.
