kevin durantKevin Durant.Wilfredo Lee/APApple‘s $1 billion push into original TV programming has gotten off to a slow start. 

The Wall Street Journal reported on Saturday that quality control issues from Apple CEO Tim Cook have largely been responsible for the company’s delayed production of the more than dozen shows it has ordered.

Cook reportedly scrapped Dr. Dre’s original series, “Vital Signs,” (which was already shot) over concerns about explicit scenes that included cocaine use, an orgy, and “drawn guns.” 

Several other shows have faced delays as Apple seeks to keep “gratuitous sex, profanity or violence” from its service’s original content, a family-friendly approach that reportedly has the company’s own employees referring to the company’s project as an “expensive NBC,” according to WSJ. 

Apple first had a brief, initial run of shows last summer with the release of the unscripted series “Planet of the Apps” and “Carpool Karaoke.” But the company shifted its course in June 2017 when it hired former Sony Pictures Television presidents Jamie Erlicht and Zack Van Amburg to head its original programming.

Since then, the company has announced the production or development of 17 original, scripted series — including a biographical drama on NBA all-star Kevin Durant’s youth, an animated show from the creator of “Bob’s Burgers,” and an untitled series from M. Night Shyamalan.

None of those 17 upcoming series has a release date yet.

Here are the 19 original shows that Apple is producing in its push into TV (including two that have already been released):
