From what i've seen on billboards they seem to go for whatever extension is free, not being too fussed (but .com is the most popularly seen. Then .net, then .cn. - probably due to the price difference) .

Still many many companies using some god awful domains though. Seen some websites advertised using what looks like 8-9 random letters (actual the first letter of each pinyin character in a name) some using 10-12 digit telephone numbers as websites. On the up side it seems that IDNs are definetely hitting the mainstream in advertisements, and hopefully spell the end to the trend of using these random looking ASCII domains currently being used.
