DEERFIELD BEACH, FL–( EMWNews – March 31, 2008) – CHDT Corporation, a Florida corporation

(OTCBB: CHDO) announced today that the company’s wholly owned subsidiary,

Overseas Building Supply(OBS), will be re-branded as a new consumer

electronic products company called Black Box Innovations, LLC. (BBI)

Management’s decision was based on the deepening decline in the housing and

construction industries which has resulted in the inability of OBS to

successfully penetrate the building supply market.

Black Box Innovations will focus on bringing innovative technology to

consumer products. The initial products under the Black Box Innovations

banner are well underway and the first product in a line that focuses on

organizing personal data, while providing both mobility and security, is

the Personal Pocket Safe™.

The Personal Pocket Safe™ organizes personal vital records — from

financial accounts and insurance policies to warrantees and passwords.

This critical information is safely contained in a PIN protected smart

drive, complete with 256-bit AES encryption and other layers of security

that ensure only the owner has access to the information the Personal

Pocket Safe™ contains.

“It is imperative that all our subsidiaries contribute to our bottom line

and with that in mind we have opted to use our existing OBS corporate

structure to launch a new and exciting subsidiary for CHDT Corp.,” said

CEO, Stewart Wallach. “We anticipate rolling out our first two products in

the first half of 2008 and have a substantial roadmap in place, which will

deliver new products to retail at a rapid pace,” he said.

this press release and risks associated with any investment in CHDT, which

is a small business concern and a “penny stock company” and, as such, a

highly risky investment suitable for only those who can afford to lose such

investment, should be evaluated together with the many uncertainties that

affect CHDT’s business, particularly those mentioned in the cautionary

statements in current and future CHDT’s SEC Filings.
