Study: Use of online messaging and social media apps spiked during COVID-19 pandemic The use of online messaging and social media apps among Singapore residents has spiked during the COVID-19 pandemic, a Nanyang Technological University, Singapore (NTU Singapore) study has found. Three in four respondents (75%) said that their use of WhatsApp during the pandemic increased. This was followed by Telegram (60.3%), Facebook (60.2%) and Instagram (59.7%). Accompanying this spike is videoconferencing fatigue, found the NTU Singapore study, which surveyed 1,606 Singapore residents from 17 to 31 December last year. Nearly one in two Singapore residents (44%) said they felt drained from videoconferencing activities, which became more frequent during the COVID-19 outbreak.
