You'll need to use the code "GIFT" when you're signing up to take advantage of the offer. It'll work for both the limited commercials and ad-free plans on the service.
Streaming services regularly offer free trials for their platforms -- the CBS All Access one is often for seven days instead of a month. Millions of people are suddenly stuck at home and looking for something to do, so burning through a series or two should keep you occupied.
With tens of thousands more TV episodes and up to 1,000 movies heading to CBS All Access later this year, ViacomCBS will be hoping people will stick around for those by becoming paid subscribers after the free month is over. There's already plenty of Star Trek material on tap for Trekkers, though. Along with Picard, Discovery and Short Treks are available, while the franchise has at least two more shows in the works.
