Some examples [1]:
- Frozen (2013) from Hans Christian Anderson’s Ice Queen (1845) - Revenue = $810.3 million
- Alice in Wonderland (2010) based on Lewis Carroll’s book (1865) - Revenue = $1.02 billion
- Snow White (1937) from the Brothers Grimm folk tale (1857) - Revenue = $416 million (10th highest grossing film as adjusted for inflation)
- Aladdin (1992) from a folk tale in One Thousand and One Nights (1706) - Revenue = $504 million
Then you have their lobbying:
"In 1998, Copyright was up for it’s last copyright term extension, from life +50 years to life +70 years. Disney’s Mickey Mouse copyright had accounted for up to $8 billion in revenue in 1998 when they were lobbying for copyright extension.
Disney’s Chairman, Michael Eisener personally met with then-Senate Majority Leader Trent Lott. The day Lott signed on as co-sponsor of the bill, Disney’s PAC donated to Lott’s campaign. Within a month Disney also gave $20,000 in soft money to the National Republican Senatorial Committee. Of the 13 initial sponsors of the House bill, 10 received contributions from Disney’s PAC. On the Senate side, 8 of the 12 sponsors received contributions" [2]
Protect $8B with some cheap lobbying. What a deal!
