The word appeared in passing in an article in the Guardian in February 2004, but it suddenly came to wider public attention in October. It’s a mark of its success that it has been estimated that the number of podcasting RSS channels has risen from nothing six months ago to 700,000 in February.
Podcast is the Word of the Year from the editors of the New Oxford American Dictionary. Erin McKean, the dictionary’s editor in chief, said: “Podcast was considered for inclusion last year, but we found that not enough people were using it, or were even familiar with the concept. This year it’s a completely different story.” Runners-up included bird flu, lifehack (a more efficient or effective way of completing an everyday task), reggaeton (a Latin American dance music which combines elements of reggae music with hip-hop and rap), squick (to cause immediate and thorough revulsion) and sudoku, the numbers game.
