The Birth of Free and Disrupting the Telecom Industry
Free’s parent firm, Iliad Group, was established in 1999 by Xavier Niel with the goal of upending France’s established telecom sector. Large companies like Orange, SFR, and Bouygues Telecom controlled the market at the time with exorbitant rates and long-term agreements. Niel recognised a chance to defy these conventions by providing high-tech, reasonably priced services without a contract.
Key Milestones of Free:
- 2002: introduced Freebox, a ground-breaking broadband bundle that was less expensive than rivals and featured phone, TV, and internet services.
- 2012: entered the mobile market by launching Free Mobile, which offered plans for as little as €2 a month, significantly lowering costs throughout the sector.
- 2020: continued its dedication to innovation by expanding into 5G services.
Millions of customers benefited from Niel’s low-cost, high-quality strategy, which also changed the French telecom market by forcing rivals to reduce their pricing.
