Other milestones:
Firework sold over 500k in one week, making it the 2nd highest weekly sale of a female artist, 4th overall.
In second place with 8 #1's on the Mainstream Top 40 (Pop songs)
Hot n Cold entered the German Singles Chart at number 2 due to high digital download sales. This is the highest entry ever of a single based on downloads alone in Germany.
In I Kissed A Girl's 3rd week it jumped to number one, in Australia, still solely off downloads, becoming only the second single to do so.
I Kissed A Girl went to the #1 spot in the UK for 5 weeks (a feat which would not be matched again until Someone Like You by Adele in 2011. Meaning it's still the biggest international)
^It actually spent four weeks at #1 on downloads alone, the longest span for any song from only downloads.
ET went to #1 on the Rhythmic Airplay Chart (R&B), she is only one of three other pop stars to do that.
ET spent 7 weeks at the top of the Hot Digital Songs chart, the 2nd most for a female artist as a lead act.
In 2nd place for most #1s (7) on the Hot Digital Songs chart
In 2nd place for most cumulative weeks at #1 (27) on the Hot Digital Songs chart. Also the artist with the shortest time frame.
The first four singles from Teenage Dream have been certified at least Gold in Germany. It's the first time the first 4 singles of an album reached (at least) Gold since Backstreet Boys' Backstreet Boys in 1995-1997 . Making Katy the only one this century (so far).
I Kissed A Girl went to the number one spot on Billboard's Hot Dance Airplay chart by three weeks, a first for a solo act with a debut single
Is there anything I missed? ^_^
