HARTFORD — Two entertainment companies, the largest tax practice in the U.S. and a major conglomerate have all announced plans to relocate or expand in Connecticut in recent days.

The production group ITV America is relocating a portion of its business operations to Stamford. ITV is the nation's largest independent producer of non-scripted entertainment content. Democratic Gov. Dannel P. Malloy also announced Friday that Wheelhouse Entertainment will use Stamford as a base of operations.

Malloy says the two firms will create a combined 450 jobs.

Malloy announced Thursday that PricewaterhouseCoopers LLC is plans to spend $20 million on expanding its Connecticut operations, making Stamford a headquarters for one tax division.

Also, 2,000 of the 35,000 new jobs the United Technology Corporation is planning to create over five years will be in Connecticut.
