Sky1 (Jetania)

Pre-launch
This logo was seen on a few newspapers in July 1977. Nothing about the channel was heard again until October that year, with a different logo than the one seen above.

1977-1984
On 11th November, 1977, Seven Premium finally launched, and aired every day from 4:00p.m. to 10:00p.m. During the channel's early years, it was a luxury that only a few households in Jetania and Kuboia had. To watch the channel, a viewing card was required. The signal for Seven Premium used to override JPC until 1987, which was controversial. Viewers could still watch JPC by taking the card out, however.

1987-1989
On 1st September 1986, it was announced that Seven Premium would be relaunched as Sky Channel in early 1987, however, the change did not take place until 6th July 1987.
