San Francisco: From Epic Games' Houseparty to Alphabet's Loon, several global startups/platforms shut shops in a year that was partially hit by the pandemic and lockdowns. Epic Games in September announced it is shutting down popular social video chat app Houseparty. Founded in 2015, Houseparty offered a way for users to participate in group video chats with friends and even play games, like Uno, trivia, Heads Up and others. Epic Games had integrated Houseparty with Fortnite, initially to allow gamers to see live feeds from friends while gaming, then later adding support to livestream gameplay directly into Houseparty. LG Electronics announced that it will be withdrawing from the mobile business. The South Korean company said in a regulatory filing that its mobile communications (MC) unit will no longer produce and sell handsets after July 31, citing a slump in business and fierce competition in the industry as the reasons behind the decision. LG's mobile business has been in the red since the second quarter of 2015. Its accumulated operating losses reached 5 trillion won ($4.4 billion) last year.
