How has copyright changed over the years?

Copyright has evolved significantly since its inception, adapting to technological advancements and changing societal needs. Originally focused on protecting authors' rights for a limited time, the scope of copyright has expanded to include digital content, software, and online platforms. The duration of protection has also lengthened, often extending to the life of the author plus many years, while enforcement mechanisms have adapted to address challenges like piracy and digital distribution. Additionally, international treaties and agreements have sought to harmonize copyright laws across borders, reflecting the global nature of content creation and consumption.
