In the 1990s what reduced the berriers to entry in the local telephone market?

In the 1990s, the Telecommunications Act of 1996 significantly reduced barriers to entry in the local telephone market by promoting competition and deregulating the telecommunications industry. It required incumbent local exchange carriers to open their networks to new competitors, allowing them to lease lines and provide services. This legislation encouraged new entrants and alternative service providers, leading to increased competition and innovation in the market. Additionally, advancements in technology and infrastructure further facilitated the entry of new players.
