From 2012, Numericable held the largest high-speed broadband network in France, including a small portion using optical fiber or FTTX.

[4][5] On March 5, 2014, Numericable, backed by its lead shareholder Altice, made an offer to buy Vivendi's SFR telecommunications affiliate, France's second largest.

[6] In 1982, the National Cable Plan was approved, with the ambitious goal of connecting one million households within five years and using the most advanced techniques of the time, including fiber-optic technology.

In order to finance the project, a public-private partnership was put in place that allowed private operators to utilise the networks set up by France Telecom to commercial ends.

Water and Sewage Treatment service providers often diversified into the cable market and used their close ties with local municipalities to win concessions.

[10] Following its national expansion strategy, Noos took over the cable television assets of French group NTL in November 2001.

In 2008, Le Câble Numericable bought WSG and MTVC, the major cable operators in Guadeloupe and Martinique.

[13] Numericable was launched as a mobile virtual network operator on May 16, 2011, advertising an ‘unlimited’ offer and highlighting its competitiveness.

To accompany its business development, Numericable launched a ‘triple play’ internet offer, costing four euros per month, on September 13, 2011.

For the eligible clients, the Box allows a high-speed internet connection (up to 200 megabytes/second) as long as it is linked to a local network.

The Box also gives its clients access to videos on-demand (VOD) and multiple social network applications, such as Twitter.

[18] On September 19, 2013, Numericable Group announced the launch of a legal and financial process aimed at the company’s initial public offering on the Paris stock exchange, regulated by NYSE Euronext.

In Portugal, Altice sold Cabovisão, due to Meo acquisition, to Apax France and it was rebranded as Nowo on 19 September 2016.

After its listing on the Paris NYSE Euronext stock exchange, Numericable main shareholders are the Luxembourg investment fund Altice (30%), which is listed under the ticker ATC on the Amsterdam NYSE Euronext stock exchange since January 2014 and is controlled and led by the French-Israeli investor and telecommunications executive Patrick Drahi, the American private-equity group Carlyle Group (26.3%), and the British private-equity firm Cinven (18.2%).
