The agency has been acquired by ISIS Equity Partners in a deal worth £10million.
TVC will use the investment to support the expansion of its digital department and online platform The Digital News Agency. It will also grow the agency's core TV and radio services.
It is the private equity firm's first PR acquisition and the deal was brokered by Livingstone Partners.
TVC co-founder and CEO Elaine Stern and co-founder Marc de Leuw will continue to lead the agency. Partner Nicholas Minter-Green has been promoted to MD.
‘This deal will give us the freedom and financial backing to continue to grow the business and invest in talent and services,' said Stern. ‘We also plan to expand our services to include social networking and digital planning teams.'
The agency currently has 35 staff and clients include Virgin Atlantic, Norwich Union and Lloyds TSB.
