Google briefly posted a doodle on its homepage Friday honoring Honinbo Shusaku, a Japanese Go player who was born on this day in 1829. The search giant apparently forgot about a much more significant event that happened on June 6: D-Day, which took place in 1944, and the Internet was outraged.

Google doodles have grown in recent years from the occasional bit of celebratory flair to a full-fledged feature managed by a team of illustrators, animators, and artists, according to the BBC. The Google doodle has a strong record for honoring a diverse array of historically and culturally important events and people.

However, the doodle subject-picking process can be fraught with controversy due to willful or accidental oversight. Google was scrutinized by Christians in 2013 for honoring Cesar Chavez's birthday over Easter, and in 2012, the company was criticized by Fox News for its lack of a Flag Day doodle.

"70th anniversary of D-Day today and Google has cupcakes as their header, shameful!" said one Twitter user. "No lie, I was disappointed when @Google didn't have a D-Day doodle. But on some Prussian poet's 167th birthday they pull out all the stops," said another.

Google originally posted the Shusaku doodle on Google.co.uk, but the company quickly removed it and added a "Remembering D-Day" line below the search box, with a link to the Google Cultural Institute's collection of historical documents, photos, and maps of the Normandy landings.
