Optimum's assets were brought together when Altice Europe acquired US cable companies Suddenlink in 2015 and Cablevision in 2016. The Suddenlink business, which management calls the "West," provides television, internet access, and phone services to roughly 4.5 million US homes and businesses located primarily in smaller markets, with major clusters in Texas, West Virginia, Idaho, Arizona, and Louisiana. The Cablevision portion, dubbed the "East," provides comparable services to about 5.5 million homes and businesses in the New York City metro area. Both regions now operate under the Optimum brand name. Altice Europe spun off Optimum, which includes both the Suddenlink and Cablevision operations, to shareholders in 2018.
