In a press release dated January 1, 1993, id Software had written that they expected Doom to be "the number one cause of decreased productivity in businesses around the world". Doom indeed became a significant problem in many workplaces, both occupying the time of employees and clogging computer networks with traffic caused by deathmatches and downloads. One common problem was that the first version of Doom used broadcast packets, degrading the performance of networks on which multiplayer Doom was being played.
