But in the article, it says

Google regularly produces altered “doodles” of its name to mark national days, sporting events and scientific anniversaries, but did not release a St George’s Day logo on April 23 last year.

“We have done St George’s Day drawings a few times before, but part of the reason for releasing them is to surprise and delight our users so we try not to do them every year,” a Google spokesman said.

“Most of the ideas come from our own staff, but we also get hundreds of requests from campaign groups and charities, and very occasionally we do ones for them.”

So was there really no logo last year?
No. There was one.
You can check the 2008 St George’s Day logo here.

Update:
Telegraph was quick to change the news article after I posted this on Twitter replying to Telegraph.
The changed lines:

Google regularly produces altered “doodles” of its name to mark national days, sporting events and scientific anniversaries, and has previously released St George’s Day logos in 2002, 2006 and 2008.

You got that?
