The UK has become the first major economy where advertisers spend more on internet advertising than on television advertising, with a record £1.75bn online spend in the first six months of the year.

The milestone marks a watershed for the embattled TV industry, the leading ad medium in the UK for almost half a century. It has taken the internet little more than a decade to become the larger sector in the UK.

UK advertisers spent £1.75bn on internet advertising in the six months to the end of June, a 4.6% year-on-year increase, according to a report by the Internet Advertising Bureau and PricewaterhouseCoopers. To put this in perspective, in 1998, when the IAB first measured internet advertising, just £19.4m was spent online.
