In Bulgaria it was formed by merging two of the biggest television operators in the country — Eurocom Cable and CableTel, in 2010.

In 1999, it built an optic-coaxial network in Sofia providing fast access to Internet using DOCSIS protocol.

In 2009 the Swedish investment fund EQT V acquires for 120 million EUR "Eurocom Cable" completely, and 70% from the then opponent "CableTel".

Later that year, "blizoo" buys the Montana's cable operator (Mont7) and Dobrich's internet provider, "Link BG".

On 12 April 2017 "blizoo" was finally flooded intro Mobiltel, with the latter taking officially care of the contracts and services of its customers.
