Nov 04 1999: Internet companies are increasingly turning to that most ubiquitous medium, the television, to spend their advertising dollars.   In the first half of this year, Internet companies spent USD400 million on television adverts and according to Competitive Media Reporting, this may reach USD1 billion by the end of the year. Last year Internet companies spent USD323 million on TV ads.   While the average price of launching a TV ad campaign is expensive, USD50 million per annum, TV networks are being creative with pricing models. For example, CBS are offering ad space for company equity and now have shares in 13 online companies.   Forrester Research recently advised online retailers to recognise the synergies between TV and the Web and coordinate advertising campaigns duly.
