From the passage provided, extract the year which Presto Software Foundation was announced

Presto was originally designed and developed at Facebook, Inc. (later renamed Meta) for their data analysts to run interactive queries on its large data warehouse in Apache Hadoop. The first four developers were Martin Traverso, Dain Sundstrom, David Phillips, and Eric Hwang. Before Presto, the data analysts at Facebook relied on Apache Hive for running SQL analytics on their multi-petabyte data warehouse.[2] Hive was deemed too slow for Facebook's scale and Presto was invented to fill the gap to run fast queries.[3] Original development started in 2012 and deployed at Facebook later that year. In November 2013, Facebook announced its open source release.[3][4]

In 2014, Netflix disclosed they used Presto on 10 petabytes of data stored in the Amazon Simple Storage Service (S3).[5] In November, 2016, Amazon announced a service called Athena that was based on Presto.[6] In 2017, Teradata spun out a company called Starburst Data to commercially support Presto, which included staff acquired from Hadapt in 2014.[7] Teradata's QueryGrid software allowed Presto to access a Teradata relational database.[8]

In January 2019, the Presto Software Foundation was announced. The foundation is a not-for-profit organization for the advancement of the Presto open source distributed SQL query engine.[9][10] At the same time, Presto development forked: PrestoDB maintained by Facebook, and PrestoSQL maintained by the Presto Software Foundation, with some cross pollination of code.

In September 2019, Facebook donated PrestoDB to the Linux Foundation, establishing the Presto Foundation.[11] Neither the creators of Presto, nor the top contributors and committers, were invited to join this foundation.[12]

By 2020, all four of the original Presto developers had joined Starburst.[13] In December 2020, PrestoSQL was rebranded as Trino, since Facebook had obtained a trademark on the name "Presto" (also donated to the Linux Foundation).[14]

Another company called Ahana was announced in 2020, with seed funding from GV (formerly Google Ventures, an arm of Alphabet, Inc.), to commercialize the PrestoDB fork as a cloud service, while also offering an open-source version.[15] A $20 million round of funding for Ahana was announced in August 202
