Social media seems to be (but actually, shouldn't be taken in isolation) the yardstick for what viewers want and think.
It's a bit like tracking, that ILR stations used to use to formulate playlists, and was one of the most unreliable and flawed ways to do it.
If tv stations take social media at its word, nothing would change, badly rating programmes would never get pulled off air, and when something really bad happens, that programme would continue like nothing had happened.
Case notes see - Show, The Jeremy Kyle and aftercare of participants.
After the terrible events earlier this year, judging by some of the comments on Twitter and Facebook and Digital Spy when ITV quite correctly dropped the show, you'd think the end of the world was heading at great speed, and only bringing back the show in its original form would save it from the huge asteroid..
