They were until 2003 when they were classified as information services. The FCC then enforced net neutrality rules by penalizing ISPs whenever they broke them until 2014 when court ruled that if ISPs are under Title I, the FCC has no control over them. In 2015 FCC reclassified them back as Title II, in 2017/2018 Pai reclassified back to Title I, but multiple states (I know that at least California and Washington) implemented their own net neutrality laws.
