Ryan Leslie, a rapper, was distraught when someone stole his computer and external hard drive because they contained some music he was writing. In an effort to retrieve his items, he created a series of YouTube videos, news articles, and social media postings in which he promised to pay $20,000 to anyone who returned his property. Leslie later increased the reward to $1 million in another YouTube video, which included the following text: In the interest of retrieving the invaluable intellectual property contained on his laptop and hard drive, Mr. Leslie has increased the reward offer from $20,000 to $1,000,000 USD.
Armin returned the computer and hard drive, but Leslie refused to pay, saying that he could not get his intellectual property from his hard drive. Did Leslie make a valid offer? Did Armin make a valid acceptance?
