For those who read the article but still don't know, from wiki pedia: Historically, the "MQ" in "MQTT" came from the IBM MQ (then 'MQSeries') product line, where it stands for "Message Queue". However, the protocol provides publish-and-subscribe messaging (no queues, in spite of the name).[8] In the specification opened by IBM as version 3.1 the protocol was referred to as "MQ Telemetry Transport".[9][10] Subsequent versions released by OASIS strictly refers to the protocol as just "MQTT", although the technical committee itself is named "OASIS Message Queuing Telemetry Transport Technical Committee".[2] Since 2013, "MQTT" does not stand for anything.[11][8]
