TV Arietu

1987-1995
In 1987, TV Arietu controversially lost its Rede Sigma affiliation after a legal battle with Rede Bahinia over the network affiliation, being forced to switch to Rede Megahertz after federal determination.

1995-1997
In 1995, TV Arietu changed affiliation to CPT after it signed a renting agreement with the network's owners for a two-year period, adopting CPT Arietu as its name.

1997-2008
In 1997, CPT Arietu reverted back to TV Arietu after signing an affiliation deal with EPT as a result of its then-affiliated station TV Itepuran being acquired by Grupo Telecord.
