Season 1

Season 1 of Talking Tom and Friends has 51 episodes and started with a pilot episode “The Audition” a couple of days before Christmas in December 2014, then started airing in April 2015 with “Untalking Tom“ and ended airing in December 2016 with the final part of the three-parter “A Secret Worth Keeping.” It has 51 episodes (52 if the pilot is counted), because it splits between Season 2, 3, 4 and 5, it's the longest-running season of the series, twice the length of each season (again counting the pilot).

Trivia

 * There is a confusion with Assertive App and Friendly Customer Service. When Assertive App first came onto YouTube, it was originally going to be the second episode, and Friendly Customer Service with the fourth. The only evidence left today are the dates of which they were uploaded. It is unknown why they changed episode order, but it is possible that Friendly Customer Service was actually the second episode produced and the Assertive App fourth.
 * This season has the most errors overall in the series.
 * This is the only season so far that has 51 episodes (52 if the pilot is counted) with subsequent seasons having 26.
 * In the first four episodes, the title sequence was missing a few sound effects, like Tom being poked by the hand, Ben being zapped by his computer, Angela's “wah-oh” and the camera snapping at the end.
 * The titles changed in "Poker Face".
