A Korean profesional baseball team has decided that I won't let a fan's physical location get in the way of watching their team live. The Hanwha Eagles have recruited 24 telepresence robots (dubbed fanbots) to help fill their stands, which does seem to be a problem given the teams record of wins and losses. The robots are capable of cheering, starting waves, and displaying text messages on their LED signs. It does bring a new element of attending a sporting event allowing you to physically interact with the environment rather than tweeting while watching the broadcast version. I do give them credit for creativity with fan engagement
I suppose this will technically increase attendance given the seat will be occupied, though not necessarily by a sentient being.
