There are many brands on Twitter that exist to uphold an image of the company they represent. As consumers, we can communicate with these accounts, voicing praise or displeasure (usually the latter). Using a simple sentiment classifier1, I scored feelings towards major brands from 0 (horrible) to 100 (excellent) once a day for five days.
The above for example, shows scores for Netflix, Hulu, and Redbox. Netflix had the lowest scores, whereas Redbox had the highest. I suspect Netflix started low with people still upset over the price hike, but it got better the next couple of days. Then on Saturday, there was a score drop, which I'm guessing was from their downtime for most of Saturday. Hulu and Redbox, on the other hand, held more steady scores.
