The launch of the campaign was timed to coincide with the beginning of the Japanese financial year, said Saito. April 1 is typically the day that large Japanese companies take in new employees. It is also close to the beginning of the school and university year, so many people are starting "new lives" at around this time of year. With the campaign, Google wants to promote itself as a way for people to get information relevant to their new lives, said Saito.

If I were an aspiring artist who had a few bucks and was trying to promote myself today might be a good day to get some exposure. One of my friends is an artist and a while ago he got to meet Pablo Picasso.
