Wikipedia:Featured topics/Main Page appearances

First appearance
For Wikipedia's 10th birthday, on January 15, 2011, the TFA slot displayed a featured topic (Featured topics/Guadalcanal Campaign), as well as a featured list and a featured sound.

A later idea
In 2014, there was a suggestion by to have a link within the TFA blurb to a featured topic of which the TFA was a part. This idea received support and was implemented. The first featured topic link was to Featured topics/Maya Angelou autobiographies, as part of the TFA blurb for All God's Children Need Traveling Shoes, on July 4, 2014. The first featured topic link within the "Today's Featured List" section was Featured topics/Battlecruisers of the world, as part of the blurb for List of sunken battlecruisers on September 26, 2014.

Within TFAs, featured topic links are generated by TFATOPIC, which can take up to two parameters as follows:



Within TFLs, featured topic links are generated by topic1 and topic2 within the TFL template. The displayed text is the same as for TFATOPIC.

Statistics
The featured topic subpages generally receive under 100 views per day. The views listed above (obtained with the tool hosted at http://stats.grok.se/) are very much above that, with a median of upwards of 2000 views. It is likely that most of these in turn lead to a similar increase of viewership in the other articles listed within the topic.
