6ter (pronounced as /fr/) is a French television network which is available free-to-air through digital terrestrial television, satellite and DSL, owned by Groupe M6.
The name's wordplay represents its positioning as M6's little "sister", and (via the ter suffix) as Groupe M6's third free-to-air entertainment channel (after M6 itself and W9).
Following the call for applications by the CSA for the launch of six new channels on the DTT, Groupe M6 presented three projects of channels : 6ter, M6 Boutique & Co and Hexa. On 27 March the CSA chose 6ter to be part of the 6 new channels to be launched on 12 December 2012 in HDTV (1080i).
In 2022, it was proposed that 6ter be sold to Altice, as part of a merger of Groupe M6 with Groupe TF1 (alongside TF1-owned channel TFX), in an attempt to alleviate competition concerns. This merger was abandoned in September 2022, leaving Groupe M6 as owners of the channel.
Like its sisters M6 and W9, 6ter has a Swiss subfeed, which air in Swiss providers and in free-to-air on satellite.
6ter's programming is family-oriented. 6ter shows magazines, documentaries, educational programs, along with children programmes, series and movies.
Until June 2016, 6ter had a weekday children morning block named Trop Toon. Since then, a few cartoons have sometimes been broadcast, notably Tintin.
