New York Giants was founded by Tim Mara with an investment of US$500 in 1925 and became one of the first teams in the then five-year-old NFL. To differentiate themselves from the baseball team of the same name, they took the name "New York Football Giants", which they still use as their legal corporate name.
In 1991, Tim Mara, grandson of the founder, was struggling with cancer and sold his half of the team to Bob Tisch for a reported $80 million. This marked the first time in franchise history the team had not been solely owned by the Mara family. In 2005, Wellington Mara, who had been with the team since its inception in 1925 when he worked as a ball boy, died at the age of 89. His death was followed two weeks later by the death of Tisch. In 2015, Wellington's widow and Giants co-owner Ann died due to complications from a head injury suffered in a fall. She was 85 years old.
