On 22 November 2012, the channel was launched in UK. On 17 June 2012, during a special event Chalo Paltai, it rebranded with a new diamond star logo.
A sister channel, Jalsha Movies, was launched 16 December 2012. In 2011, it was launched on OSN platform in Middle East. Star Jalsha was the most-watched Bangla TV channel for nine years, from 2009 to June 2018, when it was overtaken by Zee Bangla. Star Jalsha primarily competes with Zee Bangla and Colors Bangla, in addition to Aakash Aath, Rupashi Bangla and, more recently, Sun Bangla. Other Star regional-language channels before then, such as Star Vijay and Asianet, had been acquired from other companies.
Star Jalsha is a Bengali (Bangla)-language general entertainment channel (GEC) and the first regional-language (i.e., non-Hindi and non-English) channel to be launched directly by the Star TV Network.
