According to Google trends, “interest” in Twitter is about twice that of Disney. (1) As many others have mentioned, Twitter has outsize influence and visibility.
Twitter is losing money, but it could probably break even or make money if it stopped grasping for growth. It also has a strong niche, and can be expected to maintain its position for a while.
Disney is spending $ 2B per year on advertising. (2)
At a 10% discount rate, a $2 B/year perpetuity is worth $20 B.
Should Disney purchase Twitter -- making media cite tweets as stemming from “Disney’s Twitter" -- as a pure name-recognition play? Disney could add its logo to every tweet as well. If so, why aren’t other like Coca Cola in the game?
