I used to work for a company in the UK years ago, who were about the only manufacturers of teletext equipment such as inserters, etc.<p>One day we came into the office and the phones were on fire - people were giving our receptionists dogs abuse and threatening all sorts of repercussions as we&#x27;d apparently &#x27;hacked&#x27; their TVs.<p>It turned out that one of the broadcasters has done something silly with one of the inserters and reset it to factory defaults, meaning all pages were replaced with the default &#x27;Welcome to MRG Systems&#x27;, along with our phone number.<p>That was not a fun day...
