A majority of respondents (77 percent of U.S. employees and 72percent of U.K. employees) believe video calls are more effectivethan traditional voice calls, and a majority also find visualcontent easier to digest and understand than written documents andprinted materials.

However, 76 percent of companies are still relying on massemails to communicate news to their staff; 32 percent useoffice posters; 31 percent post updates on an HR intranet or webportal; and 35 percent are still relying on written documents tocommunicate news to staff.

In the U.S., only 1 in 5 companies have adopted live videobroadcasts or are providing updates via recorded videos online. Thechallenge facing many companies is inadequate IT infrastructure tosupport mass video adoption, and as such, more companies willutilize consumer websites and applications such as Skype, FacebookLive, Periscope, FaceTime, and Instagram Video.

IT departments must find ways to improve their internal networksand communication infrastructures, so businesses can improveemployee engagement, especially with millennial workers, accordingto the report.
