Pioneering social TV service Miso will shut down on October 23, according to an email sent to Miso users. The shut-down comes roughly 18 months after Miso’s assets had been acquired by Dijit, the company behind Netxguide.tv, which itself was subsequently acquired by Viggle. Miso’s users were encouraged in the good-bye email sent out this weekend to join Viggle’s service, which offers rewards for TV check-ins. However, not everyone was happy about this offer — some of Miso’s users from countries other than the U.S. have been complaining on Twitter that the Viggle app isn’t available in their market. This story was corrected at 5:25pm. An earlier version of this story incorrectly stated that Miso would shut down this week.
