Blogger launched, The U.S. Navy have to cancel a few credit cards due to hackers and the world’s first hashtag appears on Twitter. All on today’s On This Day from TestHuddle.
1999 – Blogger launches
The Internet service Blogger launches. The service was launched by Pyra Labs in 1999. It was one of the earliest dedicated blog-publishing tools. In February 2003, Pyra Labs was acquired by Google for a undisclosed sum. In 2004, Google purchased Picasa and integrated it with Blogger to allow users to post photos on the blogger.
Blogger has introduced a number of major redesigns (in 2004 and 2006) since its acquisition by Google and is in constant competition with WordPress for the most popular Blog hosting site.
2003 – U.S. Navy cancel some credit cards 
The U.S. Navy has cancelled 13,000 credit cards used for government expenses after discovering that hackers had downloaded card numbers and billing records. The card issuer, Citibank, claimed to have found no unusual activity in the card accounts though. The Navy discovered the security breach on July 30, when an Air Force Base in Ohio, detected an unusual amount of traffic in one of its servers. The bank issued new cards to replace the 13,000 that have been compromised.
2007 – The first Hashtag
The symbol that gave rise to group specific topics on Twitter was introduced on this day in 2007 by user Chris Messina (@chrismessina as @factoryjoe). He tweeted the following “how do you feel about using # (pound) for groups. As in #barcamp?” Hashtags were common in IRC before but this was the first time that they appeared on Twitter.
