The oldest newspaper that is still circulated is "Jamanak". Jamanak was established in 1908 and it's still being printed daily. The newspaper is printed in Armenian, but two pages is written in Turkish with Armenian Alphabet. There are many books written in Turkish with Armenian Alphabet. Jamanak is sold 1200 copies daily. One of the manager of the newspaper, Ara Kotcunian says that the rate is low because most Armenians cannot read or write in Armenian. Some of them even cannot speak Armenian either.
Another daily newspaper published in Armenian is "Marmara". It was established in 1940. It is sold daily between 1200-2000. This rate changes due to the season. Armenian newspapers are sold better in summer, because most Armenians scattered all over Istanbul are gethered at the Islands(especially Kinaliada) and the national feelings become stronger.
Except for these two daily newspapers, there's a theatre journal printed in Armenian Alphabet "Kulis", which is circulated twice a month. Also there's a health journal published by Surp Pirgic Armenian Hospital.
Soon, I'll put here some samples for these newspapers. Please visit again.
