They also upped the ante with a reverse stock split, completing the shell-merger + ailing company acquisition + reverse split trifecta.

Limelight Media Group yesterday said it was renaming itself Impart Media Group in order “to capitalize on the name recognition and goodwill established since 1984 by its wholly-owned subsidiary, Impart, Inc.”.
In effect, the company appears to believe that the Impart brand is stronger than the Limelight one; Impart has had more than 2400 clients in its two decades of existence.
