By the early 1980s observers saw the Pick operating system as a strong competitor to Unix. "BYTE" in 1984 stated that "Pick is simple and powerful, and it seems to be efficient and reliable, too ... because it works well as a multiuser system, it's probably the most cost-effective way to use an XT". Dick Pick founded Pick & Associates, later renamed Pick Systems, then Raining Data and TigerLogic and more recently Rocket Software. He licensed "Pick" to a large variety of manufacturers and vendors who have produced different "flavors" of Pick. The database flavors sold by TigerLogic were D3, mvBase, and mvEnterprise. Those previously sold by IBM under the "U2" umbrella are known as UniData and UniVerse. Rocket Software purchased IBM's U2 family of products in 2010 and TigerLogic's D3 and mvBase family of products in 2014.
